Minimum viable product

Dave added mixing box, time varying internal loads and set point schedule. Both models give similar results. Now works on performance improvement. With outdoor mixing, heating and cooling coil, E+ FD takes 35 s, Modelica w. dassl 1E-4 takes 200 s. Radau is about 400 s.

Heat conduction implementation

Is moving along, but Edwin is on travel today.

Scalable benchmark model

Jianjun profiled translation and computing time with JModelica and scalable model. JModelica scales linear in number of rooms if sufficient JV memory is available. 10GB needed for 100 room, hence need to work on better memory management or parallel translation or use of precompiled code.

FMI-QSS

Stuart added capability to import FMU-ME. First benchmarks started. Proposal developed for sparse FMU evaluation, to be discusses and implemented by Modelon. If proposal is efficient in JModelica, will be proposed to FMI committee.

Documentation

No update, Michael K. on travel.

OpenStudio API

No activity as Kyle worked on packaging.

Packaging

Kyle made an executable that packs JVM and JModelica compiler. Implemented C bindings for JModelica compiler. Currently works on dependencies of JVM.

General

Need to discuss with Modelon whether PyFMI can be used with C++ or Java only, to avoid having to ship Python.

New action items

None.

Previous action items

1. Michael to work on small prototypical building in Modelica.
2. Dave to add VAV model to 1 zone test case.
3. Kyle to prepare OS measures in order to move forward with how to design OS-Modelica API.
