Two figures illustrate several typical quadrilateral and tetrahedral mesh systems, respectively. It should be emphasized that the deviation between the desired and generated mesh densities and the number of transition elements or regions is minimized during mesh generation or remeshing. Additionally, mesh quality (i.e., mesh regularity and normality near the workpiece-die interface) is optimized to reduce numerical inaccuracies. As lower figure illustrates, the mesh density of the generated tetrahedrons is in close agreement with the desired mesh density, which is one of the biggest advantages of the automatic remeshing capability of AFDEX. These features help AFDEX to ensure solution accuracy and provide sophisticated simulations of precision BMF processes.
