Multiphysics coupling

QuickField is capable of multiphysics analysis, where different field problems should be simulated together and the results of one analysis are used as input data for other one. This second (“destination”) problem has to be defined on the same geometry model as the “source” problem, and may take into account the calculated field values or some derivative parameter 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 all together.
Currently the Multiphysics coupling in QuickField is supported for following types of 2D source and destination problems for specific types of imported data.
