Way to split prismatic cells on side surfaces of extruded volume to tetrahedral cells
I am using gmsh to prepare a CFD model. I notice when I reduce the mesh size field, I start to get some "zero volume" and highly skewed elements. (I use openFoam to check the mesh quality).
I also started getting some warnings like:
Info : Meshing surface 444 (Plane, Delaunay) Warning : Converged at iter. 3 for initial guess (0,0) with uv error = 6.29696e-21, but xyz error = 2000 in point (0.000000e+00, 0.000000e+00, 0.000000e+00) on surface 413 Info : [ 10%] Meshing curve 40 (Discrete curve) Warning : Closest point failed, computing from parametric coordinate
The netgen optimization seems to fix the issue. However, for my model, I need to connect an unstructured mesh to the side of an extruded surface. And netgen skips the hybrid mesh (mix of prisms and tets?).
Is there any way I can apply netgen to my model?
