High performance parallel computations of 3-D fast multipole boundary element method

A high-performance parallel computation was developed using the fast multipole boundary element method (BEM). The parallel solver is based on an adaptive new-version of the fast multipole BEM using the 3-D quadratic boundary elements and equal-accuracy quadrature. A measurement-based load-balancing scheme is used for the parallel computing targeting on the distributed architecture. Numerical examples show that this method maintains the high accuracy of high-order boundary elements, achieves satisfactory parallel efficiency for structures with irregular shapes, and significantly enhances the scale of solvable problems in comparison with the conventional BEM. The methodology provides an efficient way to solve large-scale complex engineering problems using BEM.
