On the preconditioners for fast multipole boundary element methods for 2D multi-domain elastostatics

Fast multipole method (FMM) has been successfully applied to accelerate the numerical solvers of boundary element method (BEM). However, the coefficient matrix implicitly formed by using FMM is sometimes ill-conditioned in cases when mixed boundary conditions exist, resulting in poor rate of converg...
