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.<\/p>\n

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.<\/p>\n

Was someone able to solve the problem?<\/p>\n

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

Piston ist a rigid body motion. The liner walls a deforming wall. Smoothing diffuse and local cell size remeshing.<\/p>\n
