I can do this with extrudeMesh. the problem is, that first, a 3D mesh is generated which needs a lot of RAM and makes the whole process slow. So, I tried to define the refinement regions just at the patch, that I want to extrude. Eg. width of object = 0.1, but the refinement region would only go from 0 to 0.001. this saves a lot of cells and computation time. the problem is, that my extrudeMeshDict seems so stop working with this approach. If anyone could help me with that, I would be very glad.
