Home < Hex vs Tet Mesh ComparisonsObjective:
- 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
- VTK
- Performed an initial comparison of hexahedral versus tetrahedral algorithms
- Study included comparison of hexahedral and tetrahedral meshing tools
- Evaluated the results based the following criteria
- Time to generate the mesh
- mesh quality
- Results of a static load analysis versus the number of elements
