Hello OpenModelica Community,

I would like to simulate a four cylinder row engine with modelica. For this I use the example "Modelica.Mechanics.MultiBody.Examples.Loops.EngineV6" and changed it to four cylinders with no inclination and a crank angle offset of 180 deg each (First 0, Second 540, Third 180, Fourth 360). However it turns out that the model works fine for arbitrary angle offsets other than 180 deg, but not that value itself. In that case the initial condition w(start=10) isn't recognized and the whole machine stands still.

Has anyone an idea why it doesn't work? How can I fix it?

My changes to the model:
- no gas force in "Cylinder"
- just four cylinders
- deleted "filter" and no "load2" in engine-model

Thanks for any answer
Torben

Ok, works fine now, I don't really know what went wrong.
