Magnetostatic Boundaries and Excitations
Define at least one of the following as a source of static magnetic fields:
- 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, consistently 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 voltage differential across a conduction path.
- The magnetic field on an outside surface.
- A permanent magnet.
If currents or current densities are the only sources of static magnetic fields in your model, set at least one of the following as the outer boundary:
- The default boundary conditions.
- An odd symmetry (flux tangential) boundary.
- An even symmetry (flux normal) boundary.
