Residual-Based a Posteriori Error Estimators for Algebraic Stabilizations (2404.02804v1)

Published 3 Apr 2024 in math.NA and cs.NA

Abstract: 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.
