In DENSO CORPORATION, we evaluate injector and motor performance using JMAG. According to complication of model (shape, material property) and increasing calculation steps by co-simulation with controller and circuit , it is becoming impossible to calculate in a realistic period.
So we attacked to develop HPC (High Performance Computing) method in the case of 3D-Motor model with JSOL Corporation. In the conventional JMAG, 8-core parallels computing was maximum. So we developed 128-core parallels computing using new JMAG version. As the result, the parallelization efficiency of 64-core parallels is the maximum in this model.
