Generating unstructured hybrid meshes consisting of tri-prism-tetrahedral cells
I am new to GMsh and I am trying to generate a hybrid unstructured mesh around a wing. I am using Python API to import a STEP file (using OpenCASCADE) and have successfully generated a tri-tet mesh using Delaunay algorithm. I want to generate a prism mesh around the wing surface (17 surface patches are present in the geom). Prism cells should be extruded along the normals. When i use extrude command to generate prisms, an error is displayed saying, "Could not find extruded node in surface 18".
Can you please provide an example code for generating hybrid meshes.
