Sharing topology between hexa- and tetra-mesh
Hi. I'd like to simulate a shell&tube heat exchanger. The tube side is made of 85 tubes, connected from both sides to two manifolds, as in picture (halfened geometry):
The tubes and the manifolds are different bodies grouped into one single component.
I'd like to build a conforming mesh so that the tubes are made of hexahedra and manifolds of tetrahedra, like this:
Unfortunately I'm not able to achieve this, since the mesh fails due to "Patch-conforming tetrahedron mesh failed possibly because of bad boundary mesh". I set the option "Merge" in the Shared Topology menu in SpaceClaim.
I tried also to set the option "Share" in the Shared Topology menu, but it says that it's impossible to generate a mesh.
If i set "None", edges of the meshes don't match.
Help me, please.
