An algorithm has been suggested for finding exact solutions of a nonlinear equation in partial derivatives of a divergence type which appears in the formulation of magnetostatics, hydro-and aerodynamics, quantum mechanics (stationary Schrödinger equation). The properties of smoothness of solutions in domains with corner points (piecewise smooth boundary) have been considered. The solutions with unbounded derivatives in the corner point domain have been presented on the basis of a new class of special functions.
