| Abstract: | An iterative procedure for solving large linear systems of BEMequations based on Krylov subspace method is presented in this paper. We havetested the procedure with BEM equations of two and three dimensional elasticproblems and compared with results of various iterative method. Numericalexperiments indicate that the procedure presented in this paper is efficient foriteratively solving BEM equations. |
