代数稳定化的基于残差的后验误差估计子

Residual-Based a Posteriori Error Estimators for Algebraic Stabilizations

Abhinav Jha

AI总结:

本文将AFC格式的基于残差的能量范数后验误差估计分析推广至新的代数稳定化格式,并通过二维自适应网格数值实验验证其在精度相近时效率更高。

摘要:

在本短文中,我们将针对为代数通量修正(AFC)格式[Jha20.CAMWA]定义的能量范数中基于残差的后验误差估计子的分析,扩展到新提出的代数稳定化格式[JK21.NM, Kn23.NA]。在二维自适应加密网格上进行了数值模拟,结果表明,与AFC格式相比,某种代数稳定化具有更高的效率且精度相近。

英文摘要:

In this note, we extend the analysis for the residual-based a posteriori error estimators in the energy norm defined for the algebraic flux correction (AFC) schemes [Jha20.CAMWA] to the newly proposed algebraic stabilization schemes [JK21.NM, Kn23.NA]. Numerical simulations on adaptively refined grids are performed in two dimensions showing the higher efficiency of an algebraic stabilization with similar accuracy compared with an AFC scheme.
