A hybrid SIAC -- data-driven post-processing filter for discontinuities in solutions to numerical PDEs
Soraya Terrab, Samy Wu Fung, Jennifer K. Ryan
We present a hybrid filter that is only applied to the approximation at the final time and allows for reducing errors away from a shock as well as near a shock. It is designed for…

LSIAC-MRA for Nonuniform Meshes and Applications to Mesh Adaptivity
Matthew J. Picklo, Jennifer K. Ryan
In this article we consider the extension of the (L)SIAC-MRA enhancement procedure to nonuniform meshes. We demonstrate that error reduction can be obtained on perturbed quadrilate…
