Flux-OptiStruct coupling allows making NVH analysis or static analysis in OptiStruct using the magnetic forces exported from Flux. The various concerned applications according to the coupling are: Motor, actuator, busbar ... This specific document gives the optimal workflow to follow in HyperMesh, Flux and OptiStruct to make the NVH analysis on a motor. Concerning the software version to use: Flux2018.1 (mandatory), HyperMesh 2017.2 (strongly advised) and OptiStruct 2017 (advised).
