In this paper we introduce and describe an implementation of curved (surface) geometries within the Dune framework for grid-based discretizations. Therefore, we employ the abstraction of geometries as local-functions bound to a grid element, and the abstraction of a grid as connectivity of elements together with a grid-function that can be localized to the elements to provide element local parametrizations of the curved surface.

Dune-CurvedGrid -- 用于表面参数化的 Dune 模块

在本文中，我们介绍并描述了基于网格离散化的沙丘框架内弯曲（表面）几何的实现。因此，我们将几何抽象抽象为绑定到网格元素的局部函数，将网格抽象为元素的连接性以及可以局部化到元素的网格函数，以提供曲面的元素局部参数化.
