Getting ready to generate a 3D mold mesh requires several steps, depending upon your starting point. In all cases, it is important to generate a mesh that is sufficiently fine on the internal surfaces adjacent to the part, feed system and cooling channels, yet sufficiently coarse on the outside edges to minimize the element count.
The mold mesh is prepared in a single step, or in two steps, depending upon the mold model.
Molds that have been created using the Mold Surface Wizard and which contain part inserts, mold inserts or cores, can be meshed using the 3D mold mesh. It is important that before you use the 3D mold mesh tool, you apply the Stitch Contact Interfaces tool, to ensure that there is no ambiguity at the various interfaces prior to creating the mold surface mesh.
