Abstract

We present a numerical framework for solving partial differential equations within an isogeometric context using T-splines in two and three space dimensions. Within this paper, we explain the data structures used for the implementation of deal.t (deal.II with T-splines) and main differences when using deal.t in contrast to deal.II. The authors present numerical experiments with error-based refinement (2D) and a priori refinement (3D) for scalar-valued problems. A full tutorial is given in the appendix. Since the new framework is based on deal.II, T-splines may be applied to various different PDEs.

Deal.t：在 deal.ii 框架内实现适合 T 样条的多元分析

我们提出了一个数值框架，用于在二维和三维空间中使用 Tplines 解决等几何背景下的偏微分方程。在本文中，我们解释了用于实现 deal.t（带 T 样条的 deal.II）的数据结构，以及使用 deal.t 与 deal.II 的主要区别。作者介绍了对标量值问题进行基于误差的细化（2D）和先验细化（3D）的数值实验。附录中提供了完整的教程。由于新框架基于 deal.II，T-样条曲线可应用于各种不同的 PDE。
