Structured Hexahedral Blocks

Local regions of structured hexahedral meshes of H-type can be added to the interior of the mesh and can also be connected to boundary layer meshes and CAD surfaces. These local structured meshes can cover simple domain volumes, while the more flexible hybrid meshes will cover the remaining of the domain. Special care is taken in order to ensure a smooth coupling of the two types of meshes. The mesh generator automatically takes care of interfacing the faces of the hexahedra with the faces of the hybrid mesh.

Hexahedral blocks can also be used to fill simple geometries with a purely hexahedral mesh.

Example Flow Regions:

• Vortices
• Wakes
• Mixing Regions
