Default Boundary Conditions for a 2D DC Conduction Solver

These boundary conditions are automatically defined for a DC conduction model:

• Natural boundaries are assigned to the surfaces between objects. Normal component of J and tangential component of E are continuous across discontinuity surfaces. No special conditions are imposed.
• Neumann boundaries are assigned to the outside edges of the problem region. E and J vectors are tangential to the boundary. Flux cannot cross a Neumann boundary.

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