Principle of field-circuit coupling


We refer to field - circuit coupling or coupling with the circuit equations, whenever the conductors of the finite elements domain are supplied by an external electrical circuit , and the solutions of the electrical circuit and of the magnetic field are not independent of one another.

Coupling principle

The mathematical methods of coupling depend:

  • on the one hand, on the formulation used for the magnetic field computation
  • on the other hand, on the method of analysis of the electrical circuit

In all cases, the magnetic field equations and the circuit equations are solved simultaneously.
