T,Ψ-φ_m Method for 3D Eddy Current Analysis

摘要

Since different magnetic scalar potentials are used in eddy current regions and non-eddy current regions, there isn't the cancellation error of two large variables in eddy current regions in T ,Ψ-φ_m method proposed in the paper. Discrete error of divergence of magnetic flux density brought by source current is also avoided. The method is verified through Team Workshop problem 21 model B.
