MoveDynamicMesh. Intersection of walls ( 1 fixed, 1 moving)
 

Hi all,

I want to apply a rotating movement of several degrees to a blade, but the blade is installed over a hub in a perpendicular way. The hub is fixed. If a move only the blade and the hub has a fixedValue 0, wrong cells are created at the intersection between the patches. There is a sharp change in the cell shape.

Is there any BC for the hub where the mesh can be slightly modified in the first layers to accommodate the rotation?

Can it be done in a different way?
The point is to modify the mesh inside OpenFoam without the need to re-mesh the geometry using other programs.

Best Regards
