co-simulation dymola fmu file can't be simulated by fmuchecker

Question

We are trying to test the co-simulation options of Dymola and created a fmu-file. We installed/built the FMILibrary-2.0b2 and FMUChecker-2.0b1 from www.fmi-standard.org.

I encountered an issue while trying to run the FMUChecker (fmuCheck.linux32) of a fmu-file my colleague created with Dymola. Wenn i create with my Dymola-license an fmu-file from the same Dymola model this issue is not reproducible. Because fmuCheck.linux32 runs fine without any error messages. My colleague can run both files without problems!

As it is our goal to use this option for co-simulation i tried to run the fmu file on a pc without Dymola and again i got the same error with both my fmu-copy and the one my colleague created.

Here's the Error Message

I think a fmu-file shouldn't need a Dymola license to be simulated, therefore i can't see the reason this simulation failed. What could be the reason for this strange behaviour?

Partially this is the same Error Message of this Issue Initialization of a Dymola FMU in Simulink

Any suggestions are much appreciated. Thank you.

Answer 1

It seems that dymola has not set the path variable to the license-file in ubuntu. We have done this manually by adding the following lines to .bashrc

# Dymola runtime license, path
DYMOLA_RUNTIME_LICENSE=$HOME/.dynasim/dymola.lic
export DYMOLA_RUNTIME_LICENSE

now we can simulate each others fmu-files!
