There are two ways to realize a FE-Reanalysis. One based on the created STL-file and another by creating a NURBS-Geometry (Retransition). For both methods an intersection has to be done to create functional sharp edges and surfaces on which the boundary conditions can be applied. This is done automatically during the optimisation for the STL-file (Nominal-Geometry) or manually with MSC Apex Generative Design for the NURBS-Geometry.
