As stated in my previous post, the centripetal and coriolis terms mean that a rotational frame of reference is not inertial so you cannot swap them over. If you do swap them over as you suggest the...

If you are modelling piston meshes it is common that you have to start them from top dead centre and stretch the mesh out from there. squashing the mesh up often causes mesh folding errors. So if you...

I recall posting some time ago that the best work-around for your simulation was to split your piston domains into two, a moving mesh section to model the piston motion and a stationary section for...
