Alessandro: focus on new models of the past. Need to filter which models and how space to allocate to those models. Massimo: Also agrees.
Select models, and coordinate with respective authors to see if they are interested in writing.
Michael to develop outline, select models and coordinate with prospective authors.
Alessandro gave a presentation on Aquifer Thermal Energy Storage (ATES) model that could included on the library.
Outcome of a master thesis.
Model initially developed in Matlab.
Working on Modelica implementation and on how to compute pressure drop. Alessandro has data for pressure drop. Massimo: look at permeability from ground water well pumping. "Leaky well function"
Models are now merged: https://github.com/ibpsa/modelica-ibpsa/pull/1627
Michael suggested to better show the difference between ISO13790 and BESTEST, there is a paper but maybe add to the documentation some of the charts (examples from the python script to generate results for the buildings library).
No time to work in past month.
Make SpeedControlled_Nrpm obsolete, https://github.com/ibpsa/modelica-ibpsa/issues/1704
Michael suggesting to remove models that remove RPM as in input as they behave like [0 1]. IDEAS does not use those, to be checked with Aachen.
Filip to review.
Laura close to pull request, she has some issues with cross checking the results (windows problem in getting reference results, in linux might work): https://github.com/ibpsa/modelica-ibpsa/issues/1575
No update.
https://github.com/ibpsa/modelica-ibpsa/pull/1628.
Different name for the “BlacBoxStarter”? Update on example models (running times)?
No update.
https://github.com/ibpsa/modelica-ibpsa/issues/1412
Michael work on model initialization? Difference of pressure instead of absolute pressure (in theory is better, in numerical simulation it seems inconclusive it depends on the models, scaling seems to work better) Comparison speed vs accuracy? (speed and if models actually run). Maybe use bounded attribute of real variables.
Michael waiting for OCT update.
https://github.com/ibpsa/modelica-ibpsa/pull/1602
It seems more involved than expected, since it requires handle string connectors division 0/0 on OpenModelica, in fluidflow models.
https://github.com/ibpsa/modelica-ibpsa/issues/1716
When simulating more that 1y there are some errors in the diffuse radiation calculation due to cloTim going over the validity range for some of the equations.
Jelger to review.
Expert meeting: Aim for Thursday, or for Monday morning. Half a day for expert meeting. Ideally don't overlap with BOPTEST.
Joint paper from IBPSA Modelica working group? Michael: New paper, could be an update on the library and Modelica working group? Clarifying the use of the library. (People are still citing the ANNEX) Filip: Make a list of major changes and show if there is enough to make a paper. 10 year of joined Modelica development for basic models, allows us to collaborate and hopefully expand. Maximize different expertise.
