dynamic meshing
 

i am simulating a rotating and translating rigid body in a fluid zone using dynamic mesh. the velocities are constant. the mesh works for a short while if i use a small time step like 10e-3, but after that mesh fails. it is a 3d model. can anyone give me some suggestions as to how i can custom smoothen/remesh it after a few timesteps or something like that so that my dynamic mesh doesnt fail?
