6.1.1 Examples of Acceptable Grid Topologies

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

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

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