Tetgen/Triangle for 3D/2D tet/tri meshes. These are distributed with libmesh. > 2. I want to model three different bodies, each with different material > properties.

It depends a bit on how "nice" your material properties are. If they can be described by a function, like k(x,y) then we usually just write a C++ function in that same form and call it in the integration loops. If your material properties are values read in from a file at every mesh point, then I believe the MeshData class is useful for this. > Any help would be very welcome.
