A Hybrid a–φ Cell Method for Solving Eddy–Current Problems in 3–D Multiply–Connected Domains
A hybrid $a - arphi $ Cell Method formulation for solving eddy–current problems in 3–D multiply–connected regions is presented.By using the magnetic scalar potential the number of degrees of freedom in the exterior domain with respect to the $A,V - A$ formulation, typically implemented in commercial software for electromagneti
