Good morning to all,
I hope you can help me with this problem. I want to create a wedge geometry to simulate a portion of a cylinder. The mesh requires a local cylindrical refinement. I followed these steps: 1) I created a rectagular domain using blockMesh. I set boundary types in the blockMeshDict for all patches. 2) I locally refined using topoSet and refineMesh 3) Finally I extruded the mesh using extrudeMesh, which generates a wedge of 5 degrees. The geometry looks fine but I guess there are some issues with boundaries. All the boundaries set in blockMeshDict are still present in the wedge geometry, except for the lower side of the rectagular which is now the axis of the cylinder. I guess no boundary condition has to be set fo this face but I don't know how to manage it. In this case, I didn't specify any boundary conditions and it is set as empty by default (as it is expected). If I simply cancel that boundary in the boundary.C, checkMesh returns an error. Code:
