Multi field coupling

QuickField is capable of multi-physics analysis, where different field problems should be simulated together and the results of one analysis used as input data of other one. This second problem has to be defined on the same geometry model, and may take into account the calculated loads or field source distribution, as well as other manually defined loads and boundary conditions, usual for this type of field analysis.

You can combine several coupling types in one problem. E.g., after calculating currents distribution, electrostatic and magnetic fields as separate problems based on the same model file, you can calculate temperature distribution from Joule heat and then find stresses caused by temperature, magnetic and electric forces at together.

Following coupling types are supported (for 2D formulations only):
