Sort of. You can call:
/opt/dymola/bin/dymola.sh -NoWindow someFile.mos

But you will not get any log-file output unless you call such a function from the script. And unless you call exit(), the process will keep running (and mos-scripts stop running on failure, so just adding an exit() at the end does not help).

I am sure there are some ways that work better. I just don't know them.

I see...

Thanks a lot. Actually, what I am doing now is take advantage of the dymosim.exe that dymola generates when compiling each model and call this .exe file from outside (using Python). This is another way, but it requires to compile first the model inside dymola.

I will try your suggestion.

Cheers!
