Hi,
I'm trying to brick mesh a straight pipe for OpenFOAM CFD, meaning I need a boundary layer, shell elements on the outer surfaces and a core - all hex elements. My meshing attempts up to now were only partially successful. I created a boundary layer by splitting the solid in an inner and outer pipe, then subtract one from the other, deleting the solid so I've got the inner and outer surfaces, created a surface mesh, then brick elements by using Element offset for the boundary layer. Unfortunately, the shell elements are lost in the process and I don't quite know how to create shells from the existing solids. Project nodes does not seem to be the right tool.
If someone could post a general workflow for this type of brick meshing I'd be very grateful. I've only used CFD tetramesh up to now, but OpenFOAM does seem to prefer brick elements. Unfortunately, I can't use hex core with a tetra oder penta boundary layer and transition, OpenFOAM can't handle different element types at once.
Edit: Sorry, this should have been posted in the Hypermesh subforum!
