On stationary points of filtration fields

In this article we study the qualitative investigation algorithm of pressure fixed field in porous media with arbitrary location of point's source and point's sewer with different power. The algorithm based on Newton's method and principle of argument for meromorphic functions. For accelerate computational process the investigated function is simplified by every step. The principle of argument for meromorphic functions is applied for search stationary points which have not been found by Newton's method.
