Numerical study of the independent approximation of the boundary conditions for solutions with discontinuities derivatives

This article is a sequel of other papers devoted to the numerical study of the finite difference schemes for the parabolic and elliptic equations with discontinuous coefficients.Boundary conditions in these systems are directly approximated with arbitrary order, without involving the differential equation and its continuation of the system. Theoretical justification of the method and its possible applications were discussed earlier in this journal and the goal of this article is a confirmation of convergence orders in numerical experiments on solutions with discontinuous first derivatives.
