Why do you use ANSYS Meshing for a 3D model? Fluent meshing has many advantages. For example:n1) Polyhedral elements: Due to the multiple shapes available, they adapt well to complex geometries, so that the mesh quality is high and the cell count is reduced with respect to hexaedra or tetraedra. Moreover, the poly-hexcore method combines the mentioned advamntages of polyhedra and the advantages of hexaedra (low numerical diffusion and best mesh quality).n2) It is easier to use.n3) The quality of the boundary layers is higher.n
