摘要
研究了求解一阶双曲问题的间断流线扩散法的后验误差估计 ,并依此来实现空间网格局部的合理调整 ,所给的数值算例也验证了此方法的正确性和可行性·
A posteriori error estimate of the discontinuous_streamline diffusion method for first_order hyperbolic equations was presented, which can be used to adjust space mesh reasonably. A numerical example is given to illustrate the accuracy and feasibility of this method.
