FEM element types in CalculiX
For detailed information on FreeCAD FEM elements see FEM Mes and FEM Element Types.
Segment element
seg2 FreeCAD nodes | seg3 FreeCAD nodes |
seg2 (B31) CalculiX nodes | seg3 (B32) CalculiX nodes |
FreeCAD → CalculiX, Nodes | |
N1, N2 | N1, N3, N2 |
Triangle element
Quadratic element
Tetrahedron element
The following node order is not implemented ! TODO: verify node order (do not forget getccxVolumesByFace()).
Hexahedron element
Pentahedron element
