Calculate the magnetic field distribution in case of flux focusing and flux reducing superconducting rings.
Uniform external magnetic field is defined by assigning a non-zero vector magnetic potential distribution on the simulation area boundary.
Flux expelling superconducting ring is modelled with zero vector magnetic potential boundary condition. Flux focusing superconducting ring is modelled with zero normal flux boundary condition.
