Hi,

snappyHexMesh is a great tool. Save me lots of time creating meshes. However, I do run into a problem with some situations. I am wondering if anyone has encounter the same isssue and have ways to resolve it.

As seen in the picture, I want to create a mesh "inside" the cup. I have stl file of the geometry. So, I create a simple block to contain the cup. After snappyHexMesh, I got the mesh inside the cup. But, at the point, there is only 1 patch, that is the wall of the whole geometry. I need to separate this 1 patch into: inlet, wall1, wall2, and atmospheric. How to achieve this? Sometimes, the patch I am interested in may be curved surfaces, so that patch is not always flat. Suggestions will be highly appreciated.
