Default Boundary Conditions for a Transient A-Phi Solver

These boundary conditions are automatically defined for a transient model:

• Natural boundaries are assigned to the surfaces between objects.
• Neumann boundaries are assigned to the outer surface of the problem region. J field is tangential to the boundary, and H field is normal to the boundary.

To leave a surface set to its default boundary condition, you do not need to set any boundary conditions. Deleted boundary conditions and excitations automatically reset to the default boundary conditions.
