19.9 Anisotropic Adaption

The purpose of anisotropic adaption is to refine hexahedral or prism layer cells in 3D meshes. Anisotropic adaption is considered to be more of a mesh manipulation tool rather than an adaption feature, allowing you to refine some hexahedral or prism cells that are adjacent to one or a few boundary face zones using the GUI. The hexahedral or prism cells are split in one direction each time, giving you control of the different splitting ratios, thus achieving anisotropic refinement.

Note that anisotropic adaption is different from other mesh adaption features because it only refines the mesh and cannot be coarsened after refinement.

For information on how to use anisotropic adaption, see this section in the separate User's Guide
