Abstract

Magnetic vector potential (MVP) formulations are widely used in eddy-current field computation. How to impose the gauge condition properly to ensure the uniqueness of the MVP is a key problem for researchers. In this paper, a novel MVP formulation with Coulomb Gauge for eddy-current problems using edge elements is proposed. The resultant linear matrix equation is symmetric and well-conditioned, which can be solved by direct solvers or iterative solvers efficiently. Numerical example is solved using the proposed MVP formulation, which is very promising in further engineering applications.
