Mesh Flexibility

ANSYS Fluent software provides complete mesh flexibility, including the ability to solve flow problems using unstructured meshes that can be generated about complex geometries with relative ease. Supported mesh types include triangular, quadrilateral, tetrahedral, hexahedral, pyramid, prism (wedge) and polyhedral. ANSYS Workbench allows you to import your CAD geometry, prepare it for CFD use in ANSYS DesignModeler and mesh it automatically or manually with the ANSYS Mesh component. ANSYS Meshing can also automatically extract the fluid volume from a CAD assembly and mesh it using a cut cell approach, which creates non-conformal mesh composed of hexahedral elements or by using a cut tet approach, which creates meshes composed of tetrahedral elements. Both approaches support the creation of inflation layers that are critical for accurate resolution of flow in the near-wall regions.

ANSYS Fluent also allows dynamic refinement or coarsening of the mesh based on the flow solution.
