Calculation of inducted currents using edge elements and T-T0 foromulation

The paper discusses methods of calculating induced currents in multiply connected regions containing solid conductors. In particular, the formulation based on edge elements using the electric vector potential has been considered. The equations are explained using the language of circuit theory. It is observed that the edge values of T ₀ represent the loop currents in the loops surrounding the ´holes´. It is also shown that the iterative solution may be accelerated by over-specifying the number of loop currents in the loops around the ´holes´.
