Analysis of induced electric field in human body by utility power frequency magnetic field using parallel fast multipole-accelerated boundary element method

This study investigates the efficiency of a boundary element method (BEM) enhanced by a parallelised fast multipole method (FMM) in analyses of electric field induced in the human body because of low-frequency magnetic field. The formulations of the BEM and FEM specialised for induced field analysis are presented. The scalability of the indirect BEM with the FMM in a distributed computing environment with over 100 processes is examined with pure message passing interface programming model. Numerical results of an anatomically-based human body model obtained from the BEM and FEM are discussed from the standpoints of accuracy and computational cost.
