In fleunt dynamic mesh option the remeshing does not work in boundary by deforming wall. See what happend, some people here seem to have had this problem.

The boundary cells on defined deforming wall only ceep stretching, not remeshing. Same problem on 2D Mesh. I think it is a bug. Dynamic mesh option is smoothing and remeshing with maximum cell local size with 1 mm.

Was someone able to solve the problem?


Fluent seems to have the problem with defined deforming wall by a tetrahedron mesh. In the Ansys examples shown, you always se a layering zone with hex mesh. With ist not possible here, because here overlapping the valve with the combustion chamber.
