摘要 等几何分析方法是一种直接基于CAD模型的精确几何表示进行物理性能仿真分析的新方法.文中从几何计算的视角出发,对等几何分析方法的基本框架,以及面向等几何分析的几何设计与计算的相关工作进行了介绍,重点介绍适合分析的计算域参数化、适合分析的新型样条理论、等几何配点法、面向等几何分析的并行计算等4个方向的研究进展.最后对需要进一步深入研究的关键问题进行了探讨. Isogeometric analysis method is a new approach for physical simulation and analysis based on the ex-act geometry representation of CAD models directly. From the viewpoint of geometric computing, we present a review on the basic framework of isogeometric analysis method, and the related work on geometric design and computing for isogeometric analysis. The research progress on analysis-suitable parameterization of computa-tional domain, analysis-suitable spline theory, isogeometric collocation method, parallel computing for iso-geometric analysis is introduced in details. Finally a few future directions of geometric computing problems in isogeometric analysis are presented.
