Hi ANSYS everyone!!
I have some problems and questions about dynamic mesh. Need your help please.
I made meshing with fluent meshing and, mesh type is polyhedral. For next, I want to moving bottom of cylinder and remeshing at the same time. So I compiled UDF and checked the dynamic mesh.
ANSYS user guide said that, it is recommended to use the diffusion method for polyhedral mesh, and CutCell zone remeshing method for 3D flow. In my case, my mesh is not tet and hexa so I just selected CutCell zone remeshing which is applied for all cell types.
So I checked that, and next ,moving piston(bottom) is selected for rigid body and partbody1(bottom of cylinder) is checked for deforming in dynamic mesh zones.
I think selection is right, but results failed everytime I attempted. I think it was not remeshed, it just lengthened like a pepero.
I don't know what is problem. I attached my case picture, please need your help...
+I tried to attach some pictures, but error is popped up! Without pictures, is it possible to give you a question? If it is hard to understand, I will try again. Thanks in advance!
