Thank you very much for reply. It helped. But may be you know how should i include interior or doors into a simulation if it supposed to be a single mesh?
p.s. i am sorry file was not corrupted, i just don't know how to save a scene with imported file.

i guess problem is in self penetrating edges. if that the case what is a work process?

HI
i am trying to make a car crash using cloth. simulation takes something like 12 minutes per frame even though mesh is not dense at all. i thought may be i use some wrong approach?
