摘    要:在计算流体力学(CFD)领域,几乎所有的方法都离不开网格,网格是各种数值方法的基础,网格质量的好坏直接影响数值结果的精度,甚至影响到数值计算的成败,随着计算流体力学解决的问题越来越复杂,对网格质量的要求也越来越高,传统的统一网格技术已不能适应这一不断发展的需求,为此CFD工作者发展了许多方法,如迭合网格、贴体网格和非

Abstract:In this paper, an adaptive mesh refinement technique is presented in numeri- cal solution of partial differential equations. Mainly including scanning function, refining/ derefine, and the method has been implemented based on unstructure grid and in Lagrangian or in Eulerian. Results are very helpful to the study of the numerical simulation of detonation and study of explosive performances.
Keywords:Lagrangian  Refinement/Derefinement  Adaptive meshes
