   - Hex: hexahedral mesh made entirely in PreView
   - Struct Tet: tetrahedral mesh made from the hexahedral mesh within Preview.  Has an identical number of nodes. 
   - Tet: unstructured tetrehedral mesh made entirely in PreView.
   - Python Tet:  unstructured tetrahedral mesh made with GMSH and converted into FeBio with a python script.
   - Quad Tet:  quadratic unstructured mesh made with GMSH
       + Same Elements: quadratic mesh that attempts to keep the same number of tetrahedral elements as the linear tetrehedron mesh.
       + Same Nodes: quadratic mesh that attempts to keep the same number of node the linear tetrehedron mesh.
   - sofa: preliminary attempt to simulate a similar case with the SOFA framework.
