在这篇文章中,我们给出了最近的进展,在获得有限体积和非线性双曲守恒律的间断伽辽金近似的后验误差控制。该理论是基于著名的双变量技术介绍了克鲁日科夫(数学苏联Sb.1970; 10:217-243)。后验误差控制是特别重要的,因为它可以用于设计有效的网格自适应方案。这种自适应方法的推导进行了讨论,并给出了数值实验。版权所有© 2007约翰威利父子有限公司。
In this contribution we give an overview on recent progress in obtaining a posteriori error control for finite volume and discontinuous Galerkin approximations of non‐linear hyperbolic conservation laws. The theory is based on the celebrated doubling of variables technique introduced by Kružkov (Math. USSR Sb. 1970; 10:217–243). A posteriori error control is of particular importance as it can be used for designing efficient grid adaptive schemes. The derivation of such adaptive methods is discussed and numerical experiments are given. Copyright © 2007 John Wiley & Sons, Ltd.
