Meshing with Hexahedrals using the Multi-Zone Method
The multi-zone method in ANSYS
- Gives hexahedral or box elements for certain geometries
- Chops up the domain into regions which can be "hex-meshed". These regions often have a shape that can be created though extrusion
- The default meshing method often gives a tetrahedral mesh which has lower accuracy than a hex mesh for the same number of nodes. The advantage of tetrahedrals is that you can mesh any general geometry while pure hex meshes can be created only for some geometries.
