I am looking for a detailed comparison between different Modelica compilers or simulators, including Dymola, MapleSim, Wolfran System Modler, SimulationX, OpenModelic. The details should include compatibility of mainstream commercial libraries and open-source libraries, simulation speed, support of FMI. Could anyone tell me where to find the information or existing research about this topic?
I don't think something like that exists yet because besides OpenModelica no other implementation (which all are commercial) will openly show their library coverage results. The OpenModelica library coverage you can find at: https://libraries.openmodelica.org/branches/
I agree that it would be interesting to have a comparison like this available and I think that Modelica Association should work to make it possible to provide it in the future such as they do with FMI.
