Project sponsorship.
META sponsored 5000 $ for the project maintenance and student scholarships. -
Presentation on Control Description Language (https://simulationresearch.lbl.gov/modelica/releases/v10.0.0/help/Buildings_Controls_OBC_CDL.html and ASHRAE Standard 223P https://www.ashrae.org/technical-resources/standards-and-guidelines/titles-purposes-and-scopes ).
Summary of discussion: CDL will be incorporated into IBPSA library, attention should be given to code duplication of existing control models.
- Discussions about others and future development, such as
- APPROVED
- enthalpy and energy recovery wheel
- validation of models
- CDL integration
- preconfigured controls
- NEED MORE DISCUSSION
- thermal storage
- better dynamic ground coupling of long (uninsulated) district pipes
- CHP and organic Rankine cycle
- more geothermal (horizontal loop, slinky loop, others)
- APPROVED
OpenSCALING project (Lenord Oliver and Martin Otter)
Scaling of Modelica across disciplines for large models and long simulation. Highly flexible precompiled models. UQ for large systems, carrying it from Modelica to SSP. Built-in simulation for AI support.
Streamline standards from Modelica to eFMI, FMI and SSP. Represent physics-enhanced Neural ODEs (PeNODEs). Resource aware functions - based on hardware, can act as MPC or simpler implementation, supported all through eFMI. [visionary requirement]
Providing large examples would be a very important contribution.
Proposal from Oliver Lenord have a series of session to have IBPSA MWG as a stakeholder to raise requirements what are pain point in libraries and tools set up repository with examples have updates 1/2 year
Kick-off meeting in November. If interested in an advisory board work with Oliver Lenord to issue NDA contract.
Requirements data source large models (compilation, simulation, optimization, UQ) provide library of models computationally expensive ones numerically problematic ones (see also https://ibpsa.github.io/modelica-challenge-problems/)
OpenModelica usability on existing libraries.
Increase community effort to raise issues. FMU 2.0 support working on polishing. FMU 3.0 will require full time employee 2-3 years. Try to add OpenModelica support into Modelica related proposals.
OpenModelica will create a regression testing framework for MSL. It will be extended to Modelica Association endorsed open source libraries. Possibility for IBPSA and related libraries to have external regression testing.
Continuous integration pipeline for Modelica libraries (Fabian Wuellhorst, Michael Wetter). Easy Python tool setup by Fabian to setup CI testing. Continue discussion online while waiting for solution proposed by OM
Publications. Send them to Ettore ([email protected]) for publication on the website.
