Eddy Current T-W Boundaries and Excitations
Specify at least one of the following as a source of AC magnetic fields in your model:
- The current in a conduction path, which can
be either stranded or solid.
Note: For stranded conductors, it is assumed that the current density is uniform on the cross-section of the respective conductors. Thus, the stranded option for current excitations should mostly be used only in cases where the cross-section of conductors is constant, consistent with the assumption that the respective object is a coil built with strands of wire. For this reason, conductors (coils) could be created by either sweeping around an axis using zero segments or sweeping along a path having only true surface segments in order to create a smooth surface coil having a completely uniform cross-sectional area over its entire length.
- The current density in a conductor.
- The magnetic field on an outside surface.
If currents or current densities are the only sources of AC magnetic fields in your model, set at least one outer boundary to the following:
- The default boundary conditions.
- An odd symmetry (flux tangential) boundary.
- An even symmetry (flux normal) boundary.
