TETRAHEDRAL MESHING

QUADRILATERAL MESHING

Model components: rigid bodies, shell (i.e. bone: femur, tibia, patella)

IA-FEMesh + STL:

Software: Salome 7.5.1

Method: Quadrilateral Surface Meshing

Input: STL triangulated surface geometry

Example Files:

LIMITATION: not able to control projection of block edge elements nodes to geometric edges!

HEXAHEDRAL MESHING

Model components: deformable bodies, volumetric (i.e. cartilage, ligaments, menisci)

IA-FEMesh + STL:

Salome Sub-Meshing + Hex-topology IGES:

Software: Salome 7.5.1

Method: Hexahedral Sub-Meshing (NOTE: tried Salome HEXABLOCK meshing, but face elements were twisted due to edge curvature)

Input: IGES parametric surface/volume geometry with hexahedral topology (i.e. 8 nodes, 12 edges, 6 faces)
