-title: Constant Potential Molecular Dynamics
-description: Dynamic charges for accurate molecular dynamics of charged electrodes
-importance: 1
-category: work
----
-
-A better understanding of electrochemistry would help us build better technology and fight climate change.
-In molecular dynamics simulations of electrochemical systems, however, history runs headlong into undergraduate electromagnetism.
-Molecular dynamics practitioners overwhelmingly represent atoms in molecules as particles whose charge doesn't change -- but, at a conductive surface, charge always rearranges itself so that the potential across the conductor is zero.
-
-As a developer of constant potential molecular dynamics, I strive to bring this dynamic charge rearrangement back into molecular dynamics.
-I started doing this to improve then-existing constant potential code in LAMMPS, an effort which first resulted in [USER-CONP2](https://github.com/srtee/lammps-USER-CONP2).
-Collaborating with researchers at the Technical University of Hamburg (who taught me, among other things, how to finally code properly) we then successfully included [ELECTRODE](https://docs.lammps.org/Packages_details.html#pkg-electrode) in LAMMPS, making documented and fast constant potential molecular dynamics available in a mainstream molecular dynamics package.
-
-The constant potential project continues on two fronts: speeding it up, by taking further advantage of the simplicity of electrodes with fixed position, and making it more accurate, by matching results with deeper layers of theory such as quantum-mechanical density functional theory.
-Our ultimate goal is to make constant potential molecular dynamics a simple and widely-used tool of choice for studying electrode-electrolyte interfaces.

-title: FAIR Molecular Dynamics
-description: Making molecular dynamics science more findable, accessible, interoperable, and reproducible
-importance: 3
-category: community
----
-
-Molecular dynamics is a computational science with the potential for worldwide collaboration, in comparison with wet lab techniques.
-Powerful packages are routinely accessible via open source and practitioners can get into the game with even modest computational resources.
-Thus, molecular dynamics could encourage more diversity and equity in global science.
-However, *expertise* takes longer to diffuse and share than code, hampering the creation of an open community of molecular dynamics modellers.
-
-[GO FAIR](https://www.go-fair.org/go-fair-initiative/) aims to make data Findable, Accessible, Interoperable and Reusable.
-Molecular dynamics practitioners are actively working to apply FAIR principles to molecular dynamics data and codes[^1].
-I'm the first to admit that I was previously a far less FAIR scientist, and I am working on my own data and code to improve accessibility.
-This includes maintaining this website to [document my journey](/blog/tag/doco)[^3] towards reproducible molecular dynamics science!
-
-Besides FAIR *data*, FAIRness can also be applied to the molecular dynamics *community* more generally, in terms of creating a sustainable and welcoming community.
-How can the community of open source molecular dynamics developers and practitioners improve on welcoming newcomers, quickly upskilling them remotely, and encouraging contributions back to the source code?
-What if newcomers always included their program version, extended logs, and minimal working examples when they asked questions?
-And what if experienced developers never told people "the code *is* the documentation" or "the problem exists between the keyboard and the chair", because they always had more emotionally efficient workflows available for helping others?
-I have no idea what a FAIR community would look like, but I want to do my part in making it happen!

-title: Non-Equilibrium Molecular Dynamics
-description: Theory and thermostats for molecular dynamics of flowing systems
-importance: 2
-category: work
----
-
-Molecular dynamics focuses on systems at equilibrium -- for example, by simulating a box of water molecules just "sitting there", we can learn about how the properties of a cup or an ocean of water derive from the behaviour of individual water molecules.
-However, non-equilibrium systems are both vital and fascinating to study.
-From 3D printing to nanofluidic friction to electrolyte conductivity, non-equilibrium systems are everywhere in daily life!
-
-At the [Bernhardt Group](https://aibn.uq.edu.au/bernhardt) we focus on making non-equilibrium simulations more rigorous and informative.
-Out of equilibrium, familiar daily concepts like temperature and pressure become harder to define and measure, since we must distinguish between the thermal random motion of particles and concerted flows encoding the twisting, shearing, or stretching we have imposed.
-Furthermore, a non-equilibrium simulation usually produces [dissipation](https://en.wikipedia.org/wiki/Fluctuation_theorem#Dissipation_function), which describes the irreversibility of the process and holds clues to unlocking computationally-efficient non-equilibrium molecular dynamics methods.
-
-We are currently building native molecules-first internals for [LAMMPS](https://www.lammps.org/) which will enable properly molecular thermostats and barostats for accurate non-equilibrium simulation.
-I am also studying how [constant potential molecular dynamics](/projects/CPMMD_project) affects the nanoscale friction measured between a flowing electrolyte and conductive electrodes, especially if they are charged to a specific potential difference.
-We ultimately want to accelerate non-equilibrium molecular dynamics in LAMMPS using [Kokkos](https://kokkos.org/about) to harness GPUs or other heterogeneous computing setups, in work funded by the [Pawsey Centre for Extreme scale Readiness](https://pawsey.org.au/pacer/) project VISCOUS.

-title: Research Software Engineering
-description: Carving out a niche as a scientific software engineer between academia and industry
-importance: 4
-category: community
----
-
-> Research Software Engineers are people who combine professional software expertise with an understanding of research. [^1]
-
-I drifted slowly into becoming an RSE via my work on [constant potential molecular dynamics](/projects/CPMMD_project), as I learned how to write code in C++ (the hard way!).
-My day job requires me to achieve academic goals, such as publishing papers and applying for grants -- not just for my own progress but to account to the taxpayers who pay my wages!
-But RSE work lives in a different space -- especially working on open source software, where someone has to maintain code (and communities!) without relying on commercialization for a living.
-
-So I am curious about different ways of understanding and recognizing just what, exactly, I do, and how I add value to the research community.
-Maybe it's hard to quantify what I do precisely because it's actually not worth that much!
-But more likely it's hard to quantify what I do because it provides a diffuse benefit to many people, like so much activity in the open source ecosystem.
-I am learning more everyday about this [third space](https://mdap.unimelb.edu.au/2020/09/17/defining-the-third-space/) that I inhabit and how I can grow to help more people do more things better.
-Watch this space!

- * This file contains the parser used to parse out a TeX expression from the
- * input. Since TeX isn't context-free, standard parsers don't work particularly
- * well.
- *
- * The strategy of this parser is as such:
- *
- * The main functions (the `.parse...` ones) take a position in the current
- * parse string to parse tokens from. The lexer (found in Lexer.js, stored at
- * this.lexer) also supports pulling out tokens at arbitrary places. When
- * individual tokens are needed at a position, the lexer is called to pull out a
- * token, which is then used.
- *
- * The parser has a property called "mode" indicating the mode that
- * the parser is currently in. Currently it has to be one of "math" or
- * "text", which denotes whether the current environment is a math-y
- * one or a text-y one (e.g. inside \text). Currently, this serves to
- * limit the functions which can be used in text mode.
- *
- * The main functions then return an object which contains the useful data that
- * was parsed at its given point, and a new position at the end of the parsed
- * data. The main functions can call each other and continue the parsing by
- * using the returned position as a new starting point.
- *
- * There are also extra `.handle...` functions, which pull out some reused
- * functionality into self-contained functions.
- *
- * The earlier functions return ParseNodes.
- * The later functions (which are called deeper in the parse) sometimes return
- * ParseFuncOrArgument, which contain a ParseNode as well as some data about
- * whether the parsed object is a function which is missing some arguments, or a
- * standalone object which can be used as an argument to another function.

- /* This file contains a list of functions that we parse, identified by
- * the calls to defineFunction.
- *
- * The first argument to defineFunction is a single name or a list of names.
- * All functions named in such a list will share a single implementation.
- *
- * Each declared function can have associated properties, which
- * include the following:
- *
- * - numArgs: The number of arguments the function takes.
- * If this is the only property, it can be passed as a number
- * instead of an element of a properties object.
- * - argTypes: (optional) An array corresponding to each argument of the
- * function, giving the type of argument that should be parsed. Its
- * length should be equal to `numArgs + numOptionalArgs`. Valid
- * types:
- * - "size": A size-like thing, such as "1em" or "5ex"
- * - "color": An html color, like "#abc" or "blue"
- * - "original": The same type as the environment that the
- * function being parsed is in (e.g. used for the
- * bodies of functions like \textcolor where the
- * first argument is special and the second
- * argument is parsed normally)
- * Other possible types (probably shouldn't be used)
- * - "text": Text-like (e.g. \text)
- * - "math": Normal math
- * If undefined, this will be treated as an appropriate length
- * array of "original" strings
- * - greediness: (optional) The greediness of the function to use ungrouped
- * arguments.
- *
- * E.g. if you have an expression
- * \sqrt \frac 1 2
- * since \frac has greediness=2 vs \sqrt's greediness=1, \frac
- * will use the two arguments '1' and '2' as its two arguments,
- * then that whole function will be used as the argument to
- * \sqrt. On the other hand, the expressions
- * \frac \frac 1 2 3
- * and
- * \frac \sqrt 1 2
- * will fail because \frac and \frac have equal greediness
- * and \sqrt has a lower greediness than \frac respectively. To
- * make these parse, we would have to change them to:
- * \frac {\frac 1 2} 3
- * and
- * \frac {\sqrt 1} 2
- *
- * The default value is `1`
- * - allowedInText: (optional) Whether or not the function is allowed inside
- * text mode (default false)
- * - numOptionalArgs: (optional) The number of optional arguments the function
- * should parse. If the optional arguments aren't found,
- * `null` will be passed to the handler in their place.
- * (default 0)
- * - infix: (optional) Must be true if the function is an infix operator.
- *
- * The last argument is that implementation, the handler for the function(s).
- * It is called to handle these functions and their arguments.
- * It receives two arguments:
- * - context contains information and references provided by the parser
- * - args is an array of arguments obtained from TeX input
- * The context contains the following properties:
- * - funcName: the text (i.e. name) of the function, including \
- * - parser: the parser object
- * - lexer: the lexer object
- * - positions: the positions in the overall string of the function
- * and the arguments.
- * The latter three should only be used to produce error messages.
- *
- * The function should return an object with the following keys:
- * - type: The type of element that this is. This is then used in
- * buildHTML/buildMathML to determine which function
- * should be called to build this node into a DOM node
- * Any other data can be added to the object, which will be passed
- * in to the function in buildHTML/buildMathML as `group.value`.

-
- // Nested SVGs
- // Many of the KaTeX SVG images contain a nested SVG. This is done to
- // achieve a stretchy image while avoiding distortion of arrowheads or
- // brace corners.
-
- // The inner SVG typically contains a very long (400 em) arrow.
-
- // The outer SVG acts like a window that exposes only part of the inner SVG.
- // The outer SVG will grow or shrink to match the dimensions set by CSS.
-
- // The inner SVG always has a longer, thinner aspect ratio than the outer
- // SVG. After the inner SVG fills 100% of the height of the outer SVG,
- // there is a long arrow shaft left over. That left-over shaft is not shown.
- // Instead, it is sliced off because the inner SVG is set to
- // "preserveAspectRatio='... slice'".
-
- // Thus, the reader sees an arrow that matches the subject matter width
- // without distortion.
-
- // Some functions, such as \cancel, need to vary their aspect ratio. These
- // functions do not get the nested SVG treatment.
-
- // Second Brush Stroke
- // Low resolution monitors struggle to display images in fine detail.
- // So browsers apply anti-aliasing. A long straight arrow shaft therefore
- // will sometimes appear as if it has a blurred edge.
-
- // To mitigate this, these SVG files contain a second "brush-stroke" on the
- // arrow shafts. That is, a second long thin rectangular SVG path has been
- // written directly on top of each arrow shaft. This reinforcement causes
- // some of the screen pixels to display as black instead of the anti-aliased
- // gray pixel that a single path would generate. So we get arrow shafts
- // whose edges appear to be sharper.

+ | Shern Ren Tee Spack Time 1: Getting started | Shern Ren Tee Introduction Imonitors without having to hard-reset! So it’s time to back everything up and put on a fresh Linux install – which means I might as well do everything right.
Right , in this case, means documenting my build environment. To get all evangelistic, documentation is foundational to making science more FAIR . Documentation is how a complete stranger in the scientific ecosystem can be confident that code I develop and deploy is safe to run on their computer, let alone that it will produce the right results. But guess who’s the biggest stranger in my life? It’s me ! I can count on “me” of six months or six years from now to remember practically nothing first-hand, so being all documentative and FAIRy is good for myself as much as for the wider world.
So here I am, documenting how I intend to set everything up correctly, and my first step is Spack.
Spack (and Singularity) Spack is a package manager for supercomputers, Linux, and macOS. It makes installing scientific software easy.
from: Spack
What? “Makes installing scientific software easy?” Sign me right up!
I’ll start by trialling Spack on my home computer, which I’m not turning upside down and rattling at the same time as my work desktop, to see how it goes, and then see how the process goes on my work desktop.
My specific use case is that I (with collaborators at the Hamburg University of Technology) develop the ELECTRODE package , as well as working on non-equilibrium methods in molecular dynamics with CTCMS at the University of Queensland, in the LAMMPS code. Besides developing generic code (and writing papers about it) I try to co-develop code with the INTEL package, which relies on Intel directives to go zoom zoom on Intel processors, and I am also co-developing code with the KOKKOS package to (soon) go zoom zoom on AMD GPUs on the brand new Setonix supercomputer.
This means I need to test code against at least three compiler toolchains: Intel, AMD, and good old GCC (because I’m not a monster). In addition, I also want to link against a variety of FFT and linear algebra codes (such as MKL, openBLAS, or openBLIS). This kind of wacky combinatorial development is, supposedly, what Spack is good for. We’re about to find out!

+ Spack Time 2: Pigz flying off glyphs of doom | Shern Ren Tee GCC, aka Getting Code Compiled Last I wrote, I’d typed in:
spack install lammps
An hour of computer time later, everything had Just Worked! Amazing!
Excitedly, I fired up my new install with a spack load lammps and confirmed that I had … the 2021 stable version of LAMMPS. That was exciting in itself, because this confirmed that I could smoothly switch between my custom-compiled LAMMPS versions (based off the Sept 2022 patch) and what Spack had built. Time to build the latest version:
spack install lammps@20220623
and again, everything Just Worked!
Time to get my OneAPI on Following Spack’s instructions , I installed the latest versions of Intel’s OneAPI and linked it up with Spack. That didn’t cause any trouble, which is notable because using Intel compilers on clusters has caused me grief in the past.
So now it was time to get Spack going on my next big job:
spack install lammps@20220915 %oneapi ^intel-oneapi-mkl ^intel-oneapi-mpi
Let’s unspack
@ denotes a version string – LAMMPS uses patch dates, I’m not sure what Spack does with other packages. % denotes the compiler used. ^ denotes a specific dependency, because Spack can track abstract dependencies – for example, Spack knows that LAMMPS can use any MPI, so ^intel-oneapi-mpi will tell Spack to use Intel MPI in that slot. And of course, everything compiled perfectly, and Shern coded happily ever after … not .
The glyphs of doom! The first package which refused to compile was … font-util! This was an unpleasant surprise. If you’re familiar with LAMMPS you will be wondering, why ? LAMMPS is after all a command-line-only molecular dynamics simulator, so what on earth is it doing looking for fonts? I haven’t looked at the dependency graphs but my guess is that some of the output modes probably feature fonts and therefore ask for font-util – or perhaps some other package in line has some odd dependency there.
In any case, I was staring this right in the face:

+ >> 12940 make: *** [Makefile:632: install-am] Error 2
+Urgh! Argh! What on Earth! I duly googled “failed to write cache” and dived into a morass of old, odd bug reports. Eventually, it turned out that (1) this was an old bug in fontconfig ; (2) it was being triggered by fontconfig from my Anaconda .
Of course Spack can’t solve my snake issues. But what I like about Spack is that, to me at least, it seems more transparent about the whole process. Instead of downloading wheels which magically go round and round and end up making my bus go forward, Spack is just (!) downloading source, compiling, and installing, and it happens to keep track of all its work with the hashes to show for it. I tacked on a few extra options: -v --keep-prefix to, respectively, give verbose output and keep all its temporary files around after a failed install. The install files eventually let me confirm that, yes, my Anaconda fc-cache was bugged while /usr/bin/fc-cache was updated to the latest version. After a quick and very dirty:
mv ~/anaconda/bin/fc-cache ~/anaconda/bin/fc-cache-old
+ln -s /usr/bin/fc-cache ~/anaconda/bin/fc-cache
+I was on my way!
Pigz go fly Almost immediately another package decided to lie down and not compile, and it was pigz
==> [2022-10-04-21:59:46.995345] 'make' '-j8'
+gcc -O3 -Wall -Wextra -Wno-unknown-pragmas -Wcast-qual -c -o pigz.o pigz.c
+make: gcc: Permission denied
+make: *** [<builtin>: pigz.o] Error 127
+==> Error: ProcessError: Command exited with status 2:
+ 'make' '-j8'
+
+2 errors found in build log:
+ >> 6 make: gcc: Permission denied
+ >> 7 make: *** [<builtin>: pigz.o] Error 127
+Well, not very cryptic, in that I wasn’t able to use GCC while wanting to build everything with Intel’s ICPX! That again is a good sign that Spack really was going to compile everything with ICPX or die trying.
But why was pigz asking for GCC? Again, Spack helpfully saved the source tar for me to peruse, and what should I find at the top of the Makefile but CC=gcc! Well, I don’t know how to get Spack to override the source it downloads
spack install lammps@20220915 %oneapi ^intel-oneapi-mkl ^intel-oneapi-mpi ^pigz%gcc
And … it all worked! This last command has been running the whole time I’ve been typing this entry, and it’s built (glances at other terminal) an entire new Python, LLVM for AMD GPU (which, whoops, it’s just tripped over), and (hilariously) a new fontconfig , which would have been nice to have while font-util was tripping over itself!
And instead of deciding to stop here (I can see it’s already decided that it can’t build Intel MPI without that mysterious AMD GPU LLVM, and therefore that it can’t build LAMMPS – sensible), it’s gone on now to build Rust !
If only this were a conclusion It seems that the journey goes on and on. But what I can tell is that Spack really, really does prioritize documenting a reproducible build. Of course it takes a lot of disk space to rebuild everything just to make sure it’s the same compiler throughout – but in the intended HPC use case, that totally makes sense.
Even though I’m laughing (and crying) and some of the more ridiculous errors here, I don’t think they’re Spack’s fault. If I were building LAMMPS from ground up, especially with a list of different compilers and some of the more esoteric sub-packages, I’d be running headfirst into these speed bumps too. Spack is simply doing what I want it to do – and doing an admirable job keeping track of it all, and giving me the information I need to –
dear heavens above, why is it building me a brand new NumPy ???

]]> Spack Time 1: Getting started 2022-10-01T15:32:00+00:00 2022-10-01T15:32:00+00:00 https://srtee.github.io/blog/2022/spack-time-1-getting-started Introduction Imonitors without having to hard-reset! So it’s time to back everything up and put on a fresh Linux install – which means I might as well do everything right.
Right , in this case, means documenting my build environment. To get all evangelistic, documentation is foundational to making science more FAIR . Documentation is how a complete stranger in the scientific ecosystem can be confident that code I develop and deploy is safe to run on their computer, let alone that it will produce the right results. But guess who’s the biggest stranger in my life? It’s me ! I can count on “me” of six months or six years from now to remember practically nothing first-hand, so being all documentative and FAIRy is good for myself as much as for the wider world.
So here I am, documenting how I intend to set everything up correctly, and my first step is Spack.
Spack (and Singularity) Spack is a package manager for supercomputers, Linux, and macOS. It makes installing scientific software easy.
from: Spack
What? “Makes installing scientific software easy?” Sign me right up!
I’ll start by trialling Spack on my home computer, which I’m not turning upside down and rattling at the same time as my work desktop, to see how it goes, and then see how the process goes on my work desktop.
My specific use case is that I (with collaborators at the Hamburg University of Technology) develop the ELECTRODE package , as well as working on non-equilibrium methods in molecular dynamics with CTCMS at the University of Queensland, in the LAMMPS code. Besides developing generic code (and writing papers about it) I try to co-develop code with the INTEL package, which relies on Intel directives to go zoom zoom on Intel processors, and I am also co-developing code with the KOKKOS package to (soon) go zoom zoom on AMD GPUs on the brand new Setonix supercomputer.
This means I need to test code against at least three compiler toolchains: Intel, AMD, and good old GCC (because I’m not a monster). In addition, I also want to link against a variety of FFT and linear algebra codes (such as MKL, openBLAS, or openBLIS). This kind of wacky combinatorial development is, supposedly, what Spack is good for. We’re about to find out!
(I read lots of chatter about containerizing everything, and I know Singularity / Apptainer is a big deal for eventually deploying to HPC. But, from everything I’ve read, it sounds like Spack is great on boxes which I own , and eventually containers would be important for deploying either to HPC or cloud computes.)
Installing Spack and LAMMPS So I installed Spack from GitHub using the tutorial instructions . Then, naively and straightforwardly, I typed in:
spack install lammps
and … it looks like it will take a while. This seems like a complete post now, so I’ll be back when it’s done!
]]> Shern Ren Tee I am a physicist and coder who specializes in all molecular dynamics simulations weird and unusual. I currently focus on developing new theoretical methods in constant potential molecular dynamics and nonequilibrium molecular dynamics , together with implementations in LAMMPS using C++.
I am also a passionate Research Software Engineer . Current academic pathways provide little recognition or progression for the work RSEs, like myself, put into developing open source software and making it accessible to the wider research community. I hope to somehow help to change that! I’ve joined the RSE Association of Australia and New Zealand and I’m keeping an eye out for opportunities to contribute.
When I’m not at work I am kept busy by two young children, an air fryer, and a growing assortment of obsolete devices which I will someday transform back into something useful. I regularly answer questions about molecular dynamics at the MatSci forums and Matter Modeling on StackExchange . I am a Christian scientist (not a Christian Scientist!) and I regularly worship at City Chapel, Kenmore .

To give your project a background in the portfolio page, just add the img tag to the front matter like so:
---

This image can also have a caption. It's like magic.
You can also put regular text between your rows of images. Say you wanted to write a little bit about your project before you posted the rest of the images. You describe how you toiled, sweated, bled for your project, and then… you reveal its glory in the next row of images.
You can also have artistically styled 2/3 + 1/3 images, like these.
The code is simple. Just wrap your images with <div class="col-sm"> and place them inside <div class="row"> (read more about the Bootstrap Grid system). To make images responsive, add img-fluid class to each; for rounded corners and shadows use rounded and z-depth-1 classes. Here’s the code for the last row of images above:

+ Constant Potential Molecular Dynamics | Shern Ren Tee A better understanding of electrochemistry would help us build better technology and fight climate change. In molecular dynamics simulations of electrochemical systems, however, history runs headlong into undergraduate electromagnetism. Molecular dynamics practitioners overwhelmingly represent atoms in molecules as particles whose charge doesn’t change – but, at a conductive surface, charge always rearranges itself so that the potential across the conductor is zero.
As a developer of constant potential molecular dynamics, I strive to bring this dynamic charge rearrangement back into molecular dynamics. I started doing this to improve then-existing constant potential code in LAMMPS, an effort which first resulted in USER-CONP2 . Collaborating with researchers at the Technical University of Hamburg (who taught me, among other things, how to finally code properly) we then successfully included ELECTRODE in LAMMPS, making documented and fast constant potential molecular dynamics available in a mainstream molecular dynamics package.
The constant potential project continues on two fronts: speeding it up, by taking further advantage of the simplicity of electrodes with fixed position, and making it more accurate, by matching results with deeper layers of theory such as quantum-mechanical density functional theory. Our ultimate goal is to make constant potential molecular dynamics a simple and widely-used tool of choice for studying electrode-electrolyte interfaces.

+ FAIR Molecular Dynamics | Shern Ren Tee Molecular dynamics is a computational science with the potential for worldwide collaboration, in comparison with wet lab techniques. Powerful packages are routinely accessible via open source and practitioners can get into the game with even modest computational resources. Thus, molecular dynamics could encourage more diversity and equity in global science. However, expertise takes longer to diffuse and share than code, hampering the creation of an open community of molecular dynamics modellers.
GO FAIR aims to make data Findable, Accessible, Interoperable and Reusable. Molecular dynamics practitioners are actively working to apply FAIR principles to molecular dynamics data and codesdocument my journey
Besides FAIR data , FAIRness can also be applied to the molecular dynamics community more generally, in terms of creating a sustainable and welcoming community. How can the community of open source molecular dynamics developers and practitioners improve on welcoming newcomers, quickly upskilling them remotely, and encouraging contributions back to the source code? What if newcomers always included their program version, extended logs, and minimal working examples when they asked questions? And what if experienced developers never told people “the code is the documentation” or “the problem exists between the keyboard and the chair”, because they always had more emotionally efficient workflows available for helping others? I have no idea what a FAIR community would look like, but I want to do my part in making it happen!

+ Non-Equilibrium Molecular Dynamics | Shern Ren Tee Molecular dynamics focuses on systems at equilibrium – for example, by simulating a box of water molecules just “sitting there”, we can learn about how the properties of a cup or an ocean of water derive from the behaviour of individual water molecules. However, non-equilibrium systems are both vital and fascinating to study. From 3D printing to nanofluidic friction to electrolyte conductivity, non-equilibrium systems are everywhere in daily life!
At the Bernhardt Group we focus on making non-equilibrium simulations more rigorous and informative. Out of equilibrium, familiar daily concepts like temperature and pressure become harder to define and measure, since we must distinguish between the thermal random motion of particles and concerted flows encoding the twisting, shearing, or stretching we have imposed. Furthermore, a non-equilibrium simulation usually produces dissipation , which describes the irreversibility of the process and holds clues to unlocking computationally-efficient non-equilibrium molecular dynamics methods.
We are currently building native molecules-first internals for LAMMPS which will enable properly molecular thermostats and barostats for accurate non-equilibrium simulation. I am also studying how constant potential molecular dynamics affects the nanoscale friction measured between a flowing electrolyte and conductive electrodes, especially if they are charged to a specific potential difference. We ultimately want to accelerate non-equilibrium molecular dynamics in LAMMPS using Kokkos to harness GPUs or other heterogeneous computing setups, in work funded by the Pawsey Centre for Extreme scale Readiness project VISCOUS.

+ Research Software Engineering | Shern Ren Tee Research Software Engineers are people who combine professional software expertise with an understanding of research.
I drifted slowly into becoming an RSE via my work on constant potential molecular dynamics , as I learned how to write code in C++ (the hard way!). My day job requires me to achieve academic goals, such as publishing papers and applying for grants – not just for my own progress but to account to the taxpayers who pay my wages! But RSE work lives in a different space – especially working on open source software, where someone has to maintain code (and communities!) without relying on commercialization for a living.
So I am curious about different ways of understanding and recognizing just what, exactly, I do, and how I add value to the research community. Maybe it’s hard to quantify what I do precisely because it’s actually not worth that much! But more likely it’s hard to quantify what I do because it provides a diffuse benefit to many people, like so much activity in the open source ecosystem. I am learning more everyday about this third space that I inhabit and how I can grow to help more people do more things better. Watch this space!
