Refactoring room air balance

See https://github.com/lbl-srg/modelica-buildings/issues/1129#issuecomment-393285857 for open tasks.

Fixed temporary directory.

Valgrind output.

Problem with dassl in Dymola

Both seem to run to the end (dslog.txt and .mat file look OK).

Need to see how to link to ModelicaMessage, and if needed contact [email protected] Maybe create static vs dynamic library for interface, or simply provide uncompiled C code. Compile times:

Next, work on

  • moving C from dll to code that is compiled (hence we can use ModelicaMessage and ModelicaError without problem, and avoid loading directly a dll from Modelica which we have not yet done in other models as they all use C as an interface to a dll),
  • inspect and decide whether to fix the 30 occurances of "Conditional jump or move depends on uninitialised value(s)" in libepfmi-9.0.1.so, and
  • have a permanent link to download the built binaries (once the other bug is fixed).

EnergyPlus I/O variables

Michael to merge https://github.com/lbl-srg/soep/issues/43 when approve problem is solved.

FMI-QSS

Subcontract is finalized.

Next is Objexx and Modelon to implement new specification from https://lbl-srg.github.io/soep/softwareArchitecture.html#jmodelica-integration

CI testing (funnel)

Antoine now working on integration in BuildingsPy.

Optimica license protection

Kyle to set up calls with Modelon.

Potential paths: Check diff to frozen library. Allow n models to be changed. Upgrade path to full OCT version (with access to cloud version in an integrated way).

JSON representation for OS front-end to Modelica

Jianjun to work on modelica-json parsing in Modelica rather than CDL mode.

Other items

None.

New action items

None.

Previous action items

Michael to move C code on the Modelica side from dll back to C that is compiled with the Modelica model to see if this solves the problem.

Jianjun to work on JSON representation for Modelica HVAC that could become the basis for a schema-driven editor.

Michael/Hubertus to finalize subcontracts.
