Abstract
Difference scheme of the second order of approximation for multidimens ional Poisson equation is constructed. Calculated area Omega is covere d by rectangular grid with fixed steps on each direction. Difference s cheme on the near boundary nodes is constructed on the basis of approx imation in specially chosen point. High efficiency of the method for n umerical solution in irregular areas is shown in fullfilled calculatio ns.
