Minutes

Block to overwrite control signals

Being used now in BOPTEST. Next is to make a pull request.

Regression test

Philip suggests for Simplified* examples to use from_dp = true for valves.

Next: Merge changes in BuildingsPy to its master branch.

New media R290

Developed regressions for media. Next is to impose conditions on transition.

Avoid using inverse annotation to allow result comparison across tool.

Next finish development and then put on a development branch of IBPSA. Should be finished by Aachen before end of March.

Weather data reader

Refactor based on /~https://github.com/ibpsa/modelica-ibpsa/pull/1096#issuecomment-461071638

Linearized actuator model

Use of smoothMin causes inflection point that can cause problem with Newton solver. Perform sensitivity study on the old pressure independent damper.

Work on new, pressure-dependent actuator, and put it on IBPSA branch for review/further discussion.

Library restructuring

No activity. Remove from next agenda until work starts.

Open issues

See /~https://github.com/ibpsa/modelica-ibpsa/issues

New action items

None.

Previous action items

1. Moritz to clean up examples of weather data reader in October, then do code review. See also /~https://github.com/ibpsa/modelica-ibpsa/issues/842, /~https://github.com/ibpsa/modelica-ibpsa/issues/950 and /~https://github.com/ibpsa/modelica-ibpsa/issues/1038
