基于样条空间的Hessian复形保结构离散化

Structure-preserving Discretization of the Hessian Complex based on Spline Spaces

Jeremias Arf, Bernd Simeon

摘要:

利用等几何分析的优点,即检验函数的高阶收敛性和光滑性,提出了一种新的二阶Hessian复形的离散化方法.虽然我们的方法是第一次只适用于域,通过仿射线性变换的单位立方体,我们看到在该方法中一个相对简单的方法来获得inf-sup稳定和任意快速收敛的方法为基础的Hodge-Laplacian。背景是有限元外部演算(FEEC)的理论,它指导我们保持结构的离散子复合体。

英文摘要:

We want to propose a new discretization ansatz for the second order Hessian complex exploiting benefits of isogeometric analysis, namely the possibility of high-order convergence and smoothness of test functions. Although our approach is firstly only valid in domains that are obtained by affine linear transformations of a unit cube, we see in the approach a relatively simple way to obtain inf-sup stable and arbitrary fast convergent methods for the underlying Hodge-Laplacians. Background for this is the theory of Finite Element Exterior Calculus (FEEC) which guides us to structure-preserving discrete sub-complexes.
