I study on a project about flow around a ship in Star CCM+.
When I generate mesh, I have a trouble about prism layer (boundary layer).
I generated the prism layer around the hull, but the software cannot generate prism layer around aft and pick (at those locations curvature change too much)
You can see this from the pictures at the attachments.
Does anybody know how I can solve this problem?
Thanks in advance.
Firstly, thanks for your message and please accept my apologies for the delayed response!
The prism layer mesher will automatically deactivate in areas where the extrusion would result in poor quality cells. As you noted, surface curvature can cause this to happen. This can be remedied in number of ways, depending on what your mesh requirements are. It may be possible to reduce the prism layer height that you are trying to achieve, or to refine the mesh in that area, for example.
