0引言 考虑与文[1]相同的奇异摄动两点边值问题的数值解法: Tu(x):=-εu″(x)-p(x)u′(x)=f(x),x∈(0,1);u(0)=0,u(1)=1.
For a kind of singularly perturbed two-point boundary value problems in computational fluid dynamics, standard upwind difference operator is applied. An adaptive numerical solution algorithm using equidistribution principle is given based on Richardson extrapolation method. Theoretical analysis and some numerical results are presented to validate that the algorithm is feasible and efficient.
