对流扩散反应问题的代数稳定格式

On algebraically stabilized schemes for convection-diffusion-reaction problems

Volker John, Petr Knobloch

摘要:

一个抽象的框架,使代数稳定的离散化分析在一个统一的方式。这个框架适用于这种对流扩散反应方程的离散化。该方案的定义包含一个新的限制器,它改进了标准限制器,使得局部和全局离散最大值原理在任意单纯形网格上都得到满足。

英文摘要:

An abstract framework is developed that enables the analysis of algebraically stabilized discretizations in a unified way. This framework is applied to a discretization of this kind for convection-diffusion-reaction equations. The definition of this scheme contains a new limiter that improves a standard one in such a way that local and global discrete maximum principles are satisfied on arbitrary simplicial meshes.
