Does the Stop at steady state option in SimulationCenter work? I can't seem to get it to stop even though I've tried various models that clearly have driven their derivatives to 0.
Anyway, having fun with SystemModel 4 overall. I've cobbled together a fluid library interfacing with some external property libraries. Also took advantage of the stream connector feature. It does seem to be using the OpenModelica front end (the generated code sure looks like it.) Not sure if that's a plus or a minus. So far so good.
