Thanks Wolfgang, Markus and Florian. I think I will try to get my grid into a format (hex, where I used to have tetrahedrons) that deal ii uses for 3D. Deal ii doesn't generate a mesh given points right? For me all the data is at the vertices, so I don't necessarily have to have tetrahedral elements. (Just double checking...)
