Minutes

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

simulateModel("Buildings.Experimental.EnergyPlus.Validation.OneZone", stopTime=86400, method="dassl", tolerance=1e-06, resultFile="OneZone");
   = false
simulateModel("Buildings.Experimental.EnergyPlus.Validation.OneZone", stopTime=86400, method="Lsodar", tolerance=1e-06, resultFile="OneZone");
   = false
simulateModel("Buildings.Experimental.EnergyPlus.Validation.OneZone", stopTime=86400, method="radau", tolerance=1e-06, resultFile="OneZone");
   = true

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 support-OCT@modelon.com Maybe create static vs dynamic library for interface, or simply provide uncompiled C code. Compile times:

Work on

  • moving C and header files from Buildings repo to gitlab, 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

No major activity, waiting for subcontract.

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

No discussions.

Other items

None.

New action items

Michael to test new envelope model, after Kyle posted new version.

See how to migrate C code from Buildings to EnergyPlus repository.

Previous action items

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

Michael/Hubertus/Stuart to finalize subcontracts.
