To overcome this difficulty, an iterative dual reciprocity boundary element method (DRBEM) is developed to solve Poissons equation without the need of assembling a matrix. The DRBEM procedure requires that the right hand side of Poissons equation be approximated by a radial basis function interpolation. In the iterative solution, it is found that only compactly supported, positive definite radial basis functions lead to converged results. |
