For this purpose, I made an unstructured mesh using Gmsh and then convert it to OpenFOAM. The mesh looks ok in Gmsh UI without having any error. However, while converting it to OpenFOAM and checking the mesh quality, it shows error (still 2 error for this case). I am not a super expert on Gmsh environment but can do little things. I was unable to find the solution so far after trying a couple of days. I followed this group for a long time but this is my second post here. I am really optimistic that someone from this group can find whats the actual problem in my geo file.

The mesh looks ok to me. But indeed you extrude the surface mesh with a singe layer of elements with a height that is much larger than the size of the smallest triangles, leading to very elongated prisms...
