Default Boundary Conditions for a 2D Magnetostatic Solver

These boundary conditions are automatically defined for a magnetostatic model:

• Natural boundaries are assigned to the surfaces between objects. At the interface between objects, the H tangent and B normal are continuous.
• Neumann boundaries are assigned to the outside edges of the problem region. On outer boundaries, B field is normal. As a rule, this behavior needs to be modified at least for some portions of the outer boundary to insure uniqueness of the solution.

To leave a surface set to its default boundary condition, do nothing. Deleted boundary conditions and excitations automatically reset to the default boundary conditions.
