Fluent polyhedral mesh advantages

WebThe 3D generated mesh has roughly 10 million unstructured polyhedral elements. The CFD model was proposed to simulate the spray combustion for a reverse flow annular combustor. The numerical studies consist of two reacting flow cases, and one non-reacting liquid fuel injection case. WebANSYS FLUENT can use meshes comprised of triangular or quadrilateral cells (or a combination of the two) in 2D, and tetrahedral, hexahedral, polyhedral, pyramid, or wedge cells (or a combination of these) in 3D. The choice of which mesh type to use will depend on your application. When choosing mesh type, consider the following issues: setup time.
