Computation of Source for Non-Meshed Coils in a Reduced Domain With ${A}$ – ${V}$ Formulation

The discretized source magnetic vector potential A_j, projected from source field Hs with H(curl, Ω) semi-norm, is studied for non-meshed coils with magnetic vector potential A and electric scalar potential V formulation. As a novelty, source potential A_j is computed in a reduced domain Ω_red instead of the complete domain Ω. For domains with fixed and moving parts, potential A_j can be computed on each part, for each of the related current sources, with no need to ensure its continuity between these parts.
