In this paper a new method for solving Poisson equation with Dirichlet condition on non-rectangular domains is presented . For this purpose a numerical differentiation method applying non-equidistant points are introduced . This type of numerical differentiations is used for solving Poisson problems on irregular domains.The numerical differentiation method applying non-equidistant points are introduced . The numerical results show the efficiency and performance of proposed method.
