Claim 15:
16. A non-transitory computer-readable medium encoded with instructions for commanding a processing system to implement steps for modeling core loss of an electromagnetic or of an electromechanical device, the steps comprising:
while executing a computer based electromechanical model simulator, accessing, with the electromechanical model simulator, a model of an electromechanical device having a physical deformation characterized by a cut edge associated with a material;
generating a finite element mesh including a single layer mesh for effects of core loss increase caused by the physical deformation, the single layer mesh comprising a plurality of elements each comprising: (i) one or more vertices on the cut edge and (ii) one or more separate vertices residing on an interface edge of the finite element mesh;
determining a layer depth of the single layer mesh based on a volume of a deformation region according to a cut edge model and based on a number of vertices on the cut edge and a number of the separate vertices residing on the interface edge of the finite element mesh, the cut edge model using a first calculation operation when there are (a) three vertices on the cut edge and a single vertex on the interface edge of the finite element mesh, or (b) three vertices on the cut edge surface and a single vertex on the cut edge, the cut edge model using a second calculation operation when there are two vertices on the cut edge and two vertices residing on the interface edge of the finite element mesh;
generating an electromagnetic model of the core loss of the electromechanical device by performing a finite element analysis based on the finite element mesh and the single layer mesh, wherein the core loss of the electromechanical device includes the core loss increase based on the layer depth calculated and an equivalent cut depth associated with the material.
