Consider the singular perturbed boundary value problem with turning point $$\epsilon^ 2u''+xb(x,u)u'+c(x,u)=0,\quad x\in [-1,1],$$ $$(u(- 1),u(1))=(A,B),$$ where $$\epsilon >0$$ is a small parameter, b and c are sufficiently smooth functions, A and B given constants. A finite difference scheme is employed to solve the problem numerically. A special nonequidistant mesh can be chosen which improves the convergence in numerical experiments.
