ASHRAE 140 Weather Drivers Field Trial

First round of results by the end of March.

If any volunteer for running tests, please send email to Michael Wetter. Should probably take about 2 to 3 working days.

Dynamic icons (Michael)

See notes on issue https://github.com/ibpsa/modelica-ibpsa/issues/1294

Refrigerant media (Christian)

No discussion.

CONTAM-style models (Klaas)

No discussion. Klaas sent an update, will be reviewed separate from the call.

Update on geothermal models (Massimo)

No update, works on math formulations.

Change to CVode as default solver (Michael)

No activity yet.

Pressure as state (Michael brief update)

No update since last call.

Visual enhancements of PartialTwoPort

Issue https://github.com/ibpsa/modelica-ibpsa/issues/1280 See notes on ticket.

No activity.

Progress on pull requests

All should work on the pull requests or open tickets.

New action items

Volunteers who could run the ASHRAE 140 test on the weather data reader please contact Michael Wetter.

Previous action items

Michael to make homotopyInitialization a constant, and add warning that it is deprecated if homotopy is disabled. In future releases, could remove non-homotopy alltogether.

Christian to work with Massimo on seeing what borefield measurement data Aachen could be providing.

Michael to work on converting models to CVode for Dymola CI testing.

Michael to open a ticket that would allow showing how much valves are open and how big the speed of pumps are.

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? We can add some more due to master's thesis.
