Robust fast solvers for the Poisson equation have generally been limited to regular geometries, where direct methods, based on Fourier analysis or cyclic reduction, and multigrid methods can be used. While multigrid methods can be applied in irregular domains land to a broader class of partial diffe

We present a fourth order numerical solution method for the singular Neumann boundary problem of Poisson equations. Such problems arise in the solution process of incompressible Navier-Stokes equations and in the time-harmonic wave propagation in the frequence space with the zero wavenumber. The equ
We present a direct solver for the Poisson and Laplace equations in a 3D rectangular box. The method is based on the application of the discrete Fourier transform accompanied by a subtraction technique which allows reducing the errors associated with the Gibbs phenomenon and achieving any prescribed
