Passive Conductor
Introduction
This functionality can be used currently to define some bodies as passive conductors. Defining a body as a passive conductor allows the computation of eddy currents in that body. This will enable the calculation of Joule losses due to these eddy currents in the results requests panel. Skin effect is also simulated using this functionality.
It can be used in Transient Magnetic or AC Magnetic solution to define for instance the squirrel cage in an induction machine or the heated part in an induction heating analysis.
Note: This load allows to define only a Passive
Conductor without using Circuit Designer. To set an active
conductor please use circuit Solid
Conductor component.
Note: It is mandatory to assign to the passive conductor
bodies a material with an electrical resistivity value and a soft magnetic
property.
Note: See Coils modeling for more
explanations about the different possibilities of modelling of coils.

Note: For the option Strong skin effect described
by surface impedance consult the dedicated page Conductor described by Surface Impedance.
Steps for Transient Magnetic and AC Magnetic solutions
For Transient Magnetic and AC Magnetic solutions, to define a body as passive conductor:
- Assign a Material with a soft magnetic property and an electrical resistivity to the body
- Assign the body to passive conductor load
