Mesh Types
During the process of constructing your simualtion you will need to select from different types of meshies.
Pathch Independent (Octree Algorithim)
The Patch Independent mesh method for tetrahedrons is based on the following spatial subdivision algorithm: This algorithm ensures refinement of the mesh where necessary, but maintains larger elements where possible, allowing for faster computation. Once the "root" tetrahedron, which encloses the entire geometry, has been initialized, the Patch Independent mesher subdivides the root tetrahedron until all element size requirements (that is, the prescribed local mesh sizes) are met.

1- Top down approach : The volume mesh is generated first, and this is projected on to faces and edges to create the surface mesh.
2- The faces and their boundaries (edges and vertices) are not necessarily respected if they fall under a specified tolerance, unless there is a named selection, load, boundary condition or other object scoped to them.
3- Good for gross de-featuring of dirty CAD geometries.

Patch Conforming (Delaunay Algorithm)
for Tetrahedrons Methods Control :
1- Bottom up approach : Meshing process starts from edge, face and then body.
2- All faces and their boundaries are respected and meshed.
3- Good for clean CAD geometries.
