want to create a volume tetra mesh with a inner surface trimesh as a constrain

Altair Forum User

I want to gnenerate volume tetrahedron mesh based on surface meshes. Let's say I creat a cube and a surface inside the cube, I first mesh the surface with tri mesh and then I want to mesh the whole volme base on the surface mesh I just create. Is there a way to do that in hypermesh. I tried to use 3D tetra volume mesh but it seems not wokring. Can someone give me some hints?

Hi Avirlcop

after meshing the surface, you mesh the outer of cube (tria elems)

and then enter 3D>>Tetramesh>>tetra mesh (not 'volume tetra')

change option to 'fixed trias/quads' and select all tria elems (on surfs and on cube)

then tetra elems will be mapped to the elems
