OpenModelica support IDEAS master

[b-mare]

Hi,

I tried IDEAS with OpenModelica but ran into errors with the current master version of IDEAS.

I am using OpenModelica 1.23.0~dev-56-g74cc85c on WSL2 and am trying to simulate IDEAS.Examples.Tutorial.Example1

IDEAS release 3.0.0

The model contains alias variables with redundant start and/or conflicting nominal values. It is recommended to resolve the conflicts, because otherwise the system could be hard to solve. To print the conflicting alias sets and the chosen candidates please use -d=aliasConflicts.

Despite the warnings and errors, I can still simulate the model. However, I haven't verified whether the results are correct.

The bottom line is that the 'solBus' is not present in the 'zone.ligCtr.weaBus'. I've taken a look at it myself, but at first glance, I can't pinpoint exactly where it's going wrong. Can you investigate where it's going wrong so that support for OpenModelica can be restored.

Kind regards

[Mathadon]

Francesco Casella (from the OpenModelica consortium) mentioned yesterday that OMEdit version 1.22beta3 will be released soon and that we should give that version a try. I see that in the meantime even a beta4 version exists: https://github.com/OpenModelica/OpenModelica/releases/tag/v1.22.0-dev.beta.4
I'll have a look whether I can compile that on my machine.

[Mathadon]

The same error still occurs.

[Mathadon]

I think this is an OM issue. I created an issue here: OpenModelica/OpenModelica#11373

[jelgerjansen]

@icupeiro the fact that you get this error now is due to the changes in PR #1318, which was implemented to comply with the Modelica language.
@Mathadon I thought it was an IDEAS issue because the pedantic check in Dymola also triggers errors, so I was thinking again of a violation of the Modelica language, but it might indeed be an OM problem. Thank you for creating the issue!

@b-mare, @icupeiro the error should disappear if you remove the expendable which was added in PR #1318, so this could be an intermediate solution.

[b-mare]

Indeed removing the expandable bus connectors fixes the issue for now.
Hopefully the issue can be resolved at OM.

I would like to add one more point. The examples do not currently work in OpenModelica. I haven't tried them all but example 1, 8, 9 and Heating don't work. Maybe more. I do use OM version 1.21

[jelgerjansen]

@f-beerlage this is an OM problem for which we created an issue: OpenModelica/OpenModelica#11373.
Using an older IDEAS version (commit a75d2b0 to be precise) should solve the problem for now. Please let me know if that didn't solve your errors.

[jelgerjansen]

While waiting for a fix from OM to solve this issue, I created a temporary branch BOPTEST that I will keep up to date with the latest changes in the master branch.
