An Accelerated 3D-Magnetostatic Field Computation Method With Tetrahedral Surface Integrals

Abstract

An innovative accelerated integral equation method is proposed based on a fast search algorithm for both shared and non-shared faces among mesh elements. This method successfully accelerates the computational process of solving for the tetrahedral coupling coefficients. By using the proposed accelerated integral equation method, the efficiency of constructing the coupling matrix can be improved by more than 40% without decreasing computational accuracy, as demonstrated by analytical solutions, simulations and experimental examples.
