An universal modification of the method of discrete sources (MMDS) was appliedfor solving 2D Dirichlet or Neumann boundary problem when the scatterer’s contour isa piece-wise smooth contour. The problems of accuracy, choosing auxiliary contours,stable results, location and type of contour’s break points are discussed.Keywords: Modification of the method of discrete sources, piece-wise smooth boundary,accuracy.
