Use this control to create a topology Mesh. This is an anisotropic / isotropic hybrid Mesh. The control may create a surface mesh , a surface mesh with prism layers or boundary layer elements , or a complete surface , prism and volume tetra mesh. If the polyhedral option is on , then the tetra elements will be converted to polyhedral elements. You should choose the best type of element for your solver. Note the control of the mesher is described in the global and local mesh control tools.
The topology Mesher creates an accuracte surface mesh using the CAD topology as its source. It meshes dirrectly the CAD nurb surfaces.
