Hi,

I'd like to do some basic simulations of vibrations in combustion-engines with Modelica for my studies. I'm not sure if I can get a license for SimulationX, so I wonder if OpenModelica can be an alternative.
Does anybody have experience with similiar simulations in OpenModelica? Are there possibilities to get eigenvectors/-frequencies of the MBS, and simulate in frequency-domain or do I have to do these calculations by myself?

Thanks a lot.
