Home < Hex vs Tet Mesh Comparisons

Objective:

  • Comparison of Hexahedral versus Tetrahedral meshing algorithms Orthopaedic applications

Progress:

  • Currently evaluating open source tetrahedral meshing algorithms
    • VTK
      • Slivers exist in resulting mesh
    • Netgen
      • LGPL license
      • Issues have been found regarding invalid memory references
      • Does not always converge to a solution
      • Difficult to specify desired mesh density
    • Tetgen
      • Non commercial license. Commercial license can be purchased
      • Has been used for medical applications including heart, vertebral body, and head meshes
  • Performed an initial comparison of hexahedral versus
  • Evaluate other tetrahedral meshing algorithms
