Default Boundary Conditions for a 2D Transient Solver

These boundary conditions are automatically defined for a transient model:

• Natural boundaries are assigned to the surfaces between objects. Tangential H and normal B are continuous across surfaces without current density distribution. Tangential H has a jump if the surface has current density distribution.
• Neumann boundaries are assigned to the outside edges of the problem region. Magnetic 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.
