Assigning a Dependent Boundary for a 2D Magnetostatic Solver

Assigning a dependent boundary is the second step in creating matching boundaries. The field on the independent boundary is mapped to the dependent boundary.

Note: You must define a independent boundary before creating the dependent boundaries that are associated with it. Assign dependent boundaries only to the outer surfaces of the problem region.

To set a dependent boundary:

  1. Select the section of the geometry on which you want to apply the boundary condition (typically an edge).
  2. Click Maxwell 2D > Boundaries > Assign > Matching > Dependent.
    The Dependent Boundary dialog box appears.
  3. Enter a name for the boundary in the Name box, or accept the default.
  4. Select the independent boundary to which the dependent is to be assigned from the Independent drop-down menu.
  5. In the Relation section, select one of the following to specify the field behavior on the boundary:

    Bdep = Bind

    Click this radio button if the magnetic fields on the dependent and independent boundaries have the same magnitude and direction.

    Bdep = -Bind

    Click this radio button if the magnetic fields on the dependent boundary have the same magnitude as but the opposite direction from the independent boundary.


  6. To reverse the direction of the vector, select the Reverse Direction check box.
  7. Optionally, click Use Defaults to revert to the default values in the dialog box.
  8. Click OK to assign the boundary to the selected object.
