[AMINTOFIGH]

hi
i am trying to model a slip in clutch and flywheel for 0.4s
i applied rotation to flywheel and fixed the clutch then applied prussure to clutch for engagment.
also put a contact between to engeged surfaces.
in visualization flywheel rotate and have some stresses(that i think related to rotational movment and not to friction) and clutch dosenst have any stress.why is that?
this the result for both parts
