利用变分原理的自适应网格技术被应用到两个有解析解的激波问题上 ,它能根据问题的求解 ,在解的大梯度区自动加密网格 ,从而非常成功地算出了激波。通过分析发现自适应网格技术在提高精度、减少运行时间方面显示了优良的性能。
The adaptive grid technique using variational principle is applied to two shock problems with analytic solutions. It can automatically calculate the grid according to the solution of the problem and automatically encrypt the grid in the large gradient region of the solution, so that the shock wave can be calculated very successfully . Through the analysis found that adaptive grid technology in improving accuracy, reduce operating time showed excellent performance.
