本论文是关于各向异性网格自适应及其在(2-D)结构化和非结构化网格中的应用的三篇系列文章中的第二篇。在第一篇文章中，介绍了该方法的原理、方法，并给出了该方法在这两种网格上的应用实例。第二部分详细介绍了网格自适应方法在结构化网格中的应用。自适应操作仅限于网格移动，以避免产生悬挂节点。基于没有限制性正交性约束的弹簧类比，允许宽网格运动。该自适应过程首先在分析测试案例上进行了验证，并在相关的跨声速和超音速基准上显示了其高效率。后一类算例也在自适应非结构网格上求解，为对比研究提供了参考。本系列的第三部分将在2-D非结构化测试用例上演示该方法的能力。版权所有©2002 John Wiley&Sons，Ltd.
The present paper is the second article in a three‐part series on anisotropic mesh adaptation and its application to (2‐D) structured and unstructured meshes. In the first article, the theory was presented, the methodology detailed and brief examples given of the application of the method to both types of grids. The second part details the application of the mesh adaptation method to structured grids. The adaptation operations are restricted to mesh movement in order to avoid the creation of hanging nodes. Being based on a spring analogy with no restrictive orthogonality constraint, a wide grid motion is allowed. The adaptation process is first validated on analytical test cases and its high efficiency is shown on relevant transonic and supersonic benchmarks. These latter test cases are also solved on adapted unstructured grids to provide a reference for comparison studies. The third part of the series will demonstrate the capability of the methodology on 2‐D unstructured test cases. Copyright © 2002 John Wiley & Sons, Ltd.
