| Abstract | Hierarchical matrix or H -matrix provides a data-sparse representation of system matrices resulting from the discretization of non-local operators. We are concerned with H -matrix based iterative solver in the scope of fast boundary elements methods. We focus specifically on the definition of efficient preconditioners in order to speed up the solution time of such iterative solvers and also to reduce the number of iterations as the problem complexity increases. We consider a nested outer-inner solver preconditioning strategy. The efficiency of the preconditioning will be shown with some numerical tests. Mots clés — wave propagation, H -BEM, Preconditioning, nested GMRES, outer-inner solver. |
