Refrigerant media (Christian Vering)
CONTAM-style models (Klaas)
Update on geothermal models (Massimo)
Modelica formatting script (Antoine or Nick Long)
Cooling coil model (Donghun)
Change to CVode as default solver (Michael)
Visual enhancements of PartialTwoPort (https://github.com/ibpsa/modelica-ibpsa/issues/1280)
Progress on pull requests, https://github.com/ibpsa/modelica-ibpsa/pulls
Models may be added in August 2020, need some revisions first.
To be discussed next time.
Massimo works on making response factor calculations faster. New approach scales up to 1000 boreholes, uses k-means clustering to determine how to group boreholes.
Nick presents modelica-fmt, https://github.com/urbanopt/modelica-fmt. Written in GO, works on Linux, Microsoft, OS X. Used and tweaked Antrl grammar for Modelica.
Is BSD 3-clause.
Next, start applying it to Buildings library to test if sufficiently robust, then apply to IBPSA.
See also the PR for Filip's model at https://github.com/ibpsa/modelica-ibpsa/pull/1113
Donghun presented the ongoing work on the cooling coil, dry or wet. Now works on numerical issues during mode changes, using spliceFunction and in flow reversal. Initialization is still a challenge. Testing in district model.
Next, understand advantages and limitiations of his model and Filip's model. Consider adding one state for accumulated water, which can then be used to avoid mode switch between nonlinear equations.
Filip's model has no algebraic loop.
No work on this item.
Issue https://github.com/ibpsa/modelica-ibpsa/issues/1280.
See notes on ticket.
All should work on the pull requests or open tickets.
LBL and NREL to further test modelica-fmt before applying it to a branch of the IBPSA library.
Michael to work on converting models to CVode for Dymola CI testing.
Michael to open ticket to use a scope such as shown in the top graphic of issue https://github.com/ibpsa/modelica-ibpsa/issues/1280
Klaas to make pull request for new air flow models.
Fluid Property models (RWTH) RWTH intern development of R134a, R410A, R32, R407C, R290 and R744 merge in December, Paper in March Are there further fluid models of interest? Models may be added in August 2020.
