Abstract
The purpose of this work is to analyse the performance of iterative methods for systems arising from the DRM-MD (Dual Reciprocity Method in Multi Domains). Particularly to check over the consistency and well established results yielded by this technique. To check the results and relative speed the solutions obtained through the chosen iterative methods, are also contrasted against the solutions obtained applying some direct methods, as SVD, Golub's method and Cholesky decomposition. The numerical results are also compared with a benchmark analytical solution. 1 Introduction Various research has been reported on the behaivour of the system of equations rising from Boundary Element techniques and its solution applying iterative methods. The matrices of coefficients originated from st
