Assigning an Insulating Boundary for the 3D AC Conduction Solver

This boundary condition is generally used to model very thin sheets of perfectly insulating material between touching conductors, as well as infinitely thin cracks inside conductors. Current cannot cross an insulating boundary, that is, .

To set an insulating boundary:

  1. Select the section of the geometry on which you want to apply the boundary condition (typically a face).

  2. Click Maxwell 3D > Boundaries > Assign > Insulating.

    The Insulating Boundary window appears.

  3. Enter a name for the boundary in the Name box, or accept the default.
  4. Click OK to assign the boundary to the selected object.
Note: If you apply the insulating boundary condition on sheet objects (inside conductors), always make sure that the respective entities are selected as faces and not as objects before attempting to assign the insulating boundary condition to them.
