Hello,

I want to move a piston so in the first, I tried to move a face with success, but in my problem I need to use the 6DOF option for my dynamic mesh. So I replace the profile given by another profile which I create with the same formula. But since the change, when I run a simulation, it diverged at the first time step in the 20 first iteration. So I want to know why and how to fix the problem.

Thank you for your help
