FEM - mesh

FEM mesh generation is chosen to be done directly from voxels


  • No time consuming remeshing is necessary
  • High accuracy
  • 1-1 mapping between voxels and nodes, "clean" process and result...
  • think it's more ...


  • Huge mesh

3 types of voxel mesh is used

  • Type 12: max 12 connection to each node/voxel
  • Type 18: max 18 connection to each node/voxel
  • Type 26: max 26 connection to each node/voxel


  • When automatically adding/deleting voxels/nodes - singularity may occur
    • A singular mesh will produce a matrix that is not invertible and the FEM algorithm will fail. No physical solution can be found
