OMEdit hangs on a model check

[Roel De Coninck <roeldeconinck@…>]

When I try to check my model in OMEdit, the program hangs forever (well, I assume that :-) )
When simulating from the command line, I get a stack overflow error.

The model works in Dymola.

I don't know how to figure out what's wrong. Can you tell me what to do? Or fix the issue? I attach the full library in attachment, the model is IDEAS.Thermal.Components.Storage.StorageTank

Thanks on beforehand

[Adeel Asghar]

Have you tried the check model from the command line?
The CLI also hangs because omc never return back from the stack overflow.
This is interactive environment issue rather than OMEdit.

[Roel De Coninck <roeldeconinck@…>]

I tried also a checkModel() and it also returns a stack overflow...
Something else I can try?

[Adeel Asghar]

No. The thing is omc catches the stack overflow but it doesn't return from the CORBA eventloop.

Stack overflow fixed in r18167. checkModel now works and reports that the model is balanced, but simulation fails with:

Error: An independent subset of the model has imbalanced number of equations (344) and variables (343).
// Lots of variables and equations
Error: An independent subset of the model has imbalanced number of equations (32) and variables (33).
// More variables and equations
Error: Internal error Found Equation without time dependent variables nodes[1].flowPort_a.m_flow = 0.0

Error: Internal error pre-optimization module removeSimpleEquations failed.

[Roel De Coninck <roeldeconinck@…>]

Thanks! I installed the last nightly build (r18183) and indeed the model check is fine (this model could not be simulated directly).
However, in this revision, no single model can be simulated anymore. Looks like OMEdit cannot find -lipopt and -lcoinmumps.

I add the compilation log below.
Maybe I have to create a new ticket?

That problem will be fixed in the next nightly build: See ​https://test.openmodelica.org/hudson/job/OpenModelica_LINUX_NIGHTLY_BUILD/464/ for availability.

[Roel De Coninck <roeldeconinck@…>]

wow, that was a lightning speed answer. Thanks so much.
:-)

[Martin Sjölund]

This ticket was not closed for 1.9.1, which has now been released. It was batch modified for milestone 1.9.2 (but maybe an empty milestone was more appropriate; feel free to change it).

[Martin Sjölund]

Milestone changed to 1.9.3 since 1.9.2 was released.

[Martin Sjölund]

Moved to new milestone 1.9.4

[Francesco Casella]

It seems that all reported problems were fixed, so I am closing the ticket

[Martin Sjölund]

Milestone renamed
