Split the Poisson equation into Laplace equation with non homogeneous boundary condition and Poisson equation with homogeneous boundary condition.Laplace equation with non homogeneous boundary condition is solved with separation of variable method .Poisson equation with homogeneous boundary condition solved with eigen value expansion method.
