Hi there,
I've created a mesh of a Wave Channel using wedge-shaped blocks. In the attached pictures you can see the geometry of the whole domain, the blockMeshDict and the error message of the checkMesh utility. I think the nonOrthoFaces shouldn´t be a problem. Can I also ignore the zeroAreaFaces as it's normal to have zeroAreaFaces in a wedgeshaped block? The Tutorial states these block faces would be assigned to a patch, which then can be seen as a patch with no faces in the boundary file. But there is no such patch in the boundary file for my case. Also checkMesh detects two skewFaces. I've looked at them with ParaView and they are on the downside face of the wedge-shaped block (the ZeroAreaFace) left side of the structure. (see the red line on the attached zoomed-in picture) I'm wondering:

Hi,
in my opinion you should avoid the wedge-shaped blocks. Try to create your blocks as shown in the attached image. This way you will obtain a mesh consisting of real quads/hexas only. Cutter |
