Thanks! Yes the mesh is only tet4. I went through the LibMesh code for calculating the Jacobian. I need derivatives of the basis functions, right? Is there an easy way I can do this outside LibMesh? @John: I would assume the ordering of each Tet's nodes in Sentaurus is the same, Looking closely at the Sentaurus format, they actually retain the clockwise order of edges in faces relative to the element by having a negative sign. I can try to use that information and figure out the node ordering.
