Hi Adeel,

Is there also a way of calling `setCommandLineOptions("-d=newInst")` before creating a ModelicaSystem object?

mod = ModelicaSystem()

mod.sendExpression('setCommandLineOptions("-d=newInst")')

mod.sendExpression("loadFile(cd() + \"/mymodel.mo\")")

mod.buildModel()

Because when calling ModelicaSystem('mymodel.mo', 'mymodel') it automatically creates a new OMCSession.

Kind regards,

Dear all,

When trying to run a modelica model with OMPython, I get the same error messages as I would in OpenModelica with "old frontend for code generation" enabled. Unfortunately I only got this model to work in OpenModelica with this option disables, i.e. in the new frontend.

Is there a workaround to this in OMPython? Or should I debug the model in OpenModelica using the old frontend code generation?
i'm using the latest stable dev (1.15.0).

Many thanks for the help!

Cheers,
/Glenn

PS: I've also tried to generate an FMU (this also only worked in the new frontend, but then failed with e.g. pyfmi and FMU simulator - i.e. the FMU seems corrupted).

This solved the problem indeed, many thanks for your fast reply!

Cheers,

Hi,

I've been trying to run the PhotovoltaicCoolingSystems example in the latest stable OpenModelica (1.14.1) but the compilation fails (using gcc). With the other, more simple, examples I experience no issues. Any idea what can be the problem? According to this is should work. Many thanks for your help!
