6.1.1 Examples of Acceptable Mesh Topologies

ANSYS FLUENT can solve problems on a wide variety of meshes. Figures  6.1.2- 6.1.13 show examples of meshes that are valid for ANSYS FLUENT.

O-type meshes, meshes with zero-thickness walls, C-type meshes, conformal block-structured meshes, multiblock structured meshes, non-conformal meshes, and unstructured triangular, tetrahedral, quadrilateral, hexahedral, and polyhedral meshes are all acceptable.

Note:   Though ANSYS FLUENT does not require a cyclic branch cut in an O-type mesh, it will accept a mesh that contains one.
