ABSTRACT:
We employ FMMs as a preconditioner for sparse matrix solvers. We test our FMM-based preconditioner for the conjugate gradient method for elliptic problems. Unlike most previous FMM preconditioner/solver practice, where problems with free-field boundary conditions were investigated, we apply our preconditioner to Dirichlet/Neumann boundary conditions by coupling FMM with a boundary element method. The convergence rate is compared with Jacobi, ILU, geometric multigrid, and algebraic multigrid methods. The rate of convergence of our FMM-based preconditioner is similar to that of algebraic multigrid.
