lingo Guest Posts: n/a	Hi,evreyone: I failed to preview the mesh moving in any 3D cases (translate or rotate) with dynamic mesh model.After one or two steps ,non-positive volumes appear .I decreased the step size ,but it doesn't work. I am sure the udf is ok because it works well in 2d cases.And I can see the mesh motion. Could you give me any suggestions?If you have 3D cases,I really hope that you could send me. Thank you very much! Regards lingo
