DC Conduction + Electrostatic Boundaries and Excitations
In the case of a problem when you are interested in the electric solution in both the conductors and the insulators, you can define a DC Conduction + Electrostatic solution type. The Insulator/Conductor threshold defines which objects are conductors or insulators. The solver first solves the conduction problem in all conduction paths and then, using the calculated voltage on the conductors as a voltage excitation, computes the electrostatic field in the insulators. As a consequence, you can define the DC-conduction excitations and boundary conditions in the conducting regions and the electrostatic excitations and boundary conditions in the insulators.
