I generated 3D anisotropic meshes with my own metrics and mmg3d. I found that the tetrahedron segmentation speed is too fast. How does mmg3d control the number of tetrahedrons? hoffman educationWebMMG3D is a tetrahedral fully automatic remesher. Starting from a tetrahedral mesh, it produces quasi-uniform meshes with respect to a metric tensor field. This tensor prescribes a length and a direction for the edges, so that the resulting meshes will be anisotropic. hoffman ed2pbmWeb31 mrt. 2024 · The mmg3d application allows to discretize and optimize an implicitly defined surface (which mean a surface defined by a level-set function).
