      ANSYS Fluent has the capability to convert globally or locally the cells of a pre-existing grid into polyhedral cells. The generation of polyhedral grids is now natively possible in ANSYS Fluent Meshing and is a valuable solution compared to a posteriori conversion. Polyhedral are known to show some numerical properties due to lower cell count compared to tetraedral grid: – Less memory required – Faster time to obtain solution Nevertheless, what is the impact of polyhedra on the calculation of gradients? See attached document for further elements on this topic.
