Summary A numerical method previously applied to linear two‐point boundaryvalue problems of boundary layer type is extended to some non‐linear problems.Discretization of the differential equation leads to a set of non‐linear algebraicequations, which is solved by a modified Newton's method; both the meshspacing and the boundary layer parameter are iteratively adjusted during thesolution process. Several examples are discussed; one of these concerns theproblem of shock wave formation in a supersonic nozzle.
