      The paper examines some issues related to designing algorithms for regular difference grid construction with systems of el 1iptic-type differential equations. Making the associated mapping univalent in the case of complicated-shape region is an extremely difficult problem. Achieving a sufficient mapping flexibility requires that governing functions should be introduced into the equations used. Nonuniform rectangular and polar grids are used to study advantages and disadvantages of various algorithms.
