Types of boundaries for vector potential

For components of the vector potential used for calculation of the inductive heating zero Dirichlet values should be set for both components at the whole external boundary of the computational domain with exception of the symmetry axis.

The computation of the inductive heating may be executed also if no boundary conditions are set and there are electrically conducting materials dissipating the energy of the electromagnetic field. But in this case the electromagnetic field propagates outside of the considered domain.

In case if the Dirichlet boundary condition is set for one component at any line, another component should also accept the Dirichlet boundary condition.
