Hybrid-Mixed Formulation for Static-Current Flow Problem Compared with Conventional Formulation

摘要

The electric scalar potential formulation is generally used to determine the static-current flow. This formulation is not naturally compatible with the electric vector potential formulation (T-Φ). This incompatibility comes from the summation of static and eddy currents whose functional spaces are different. In this paper, we propose an alternative approach based on mixed elements to obtain the current densities in the space H(div) and compare them to the electric scalar potential formulation.
