Abstract
A three-dimensional (3-D) finite element formulation for calculating Meissn er currents in superconductors is presented. The authors have chosen a magn etic vector potential formulation, which also enables them to simulate ferr omagnetic shielding. The equations are written so that the problem can be s olved by the use of a conjugate gradient algorithm without preconditioning, Numerical results on normal-superconductor junctions and on superconductin g lines are compared with analytical solutions.
