Parallel Multipolar algorithm for the Indirect Boundary Element Numerical solution of Stokes Flow Problems
A multipolar expansion technique is applied to the indirect Boundary Element Method formulation in order to solve Stokes Flow problems. Due to the nature of the algorithm, it is necessary to resort to the use of an iterative solver for the resulting algebraic linear system of equations. In comparison with the direct BEM formulation, the indirect formulation is more stable with iterative solvers, and does not need to be preconditioned to obtain a fast rate of convergence. A parallel implementation is designed to take advantage of the natural domain decomposition of fast multipolar techniques and bring further improvement. A good result in memory saving and computing time is obtained that enable us to run huge examples which are prohibitive for traditional BEM implementations.
