What is SIAC? 

The Smoothness-Increasing Accuracy-Conserving (SIAC) filter is a post-processing tool designed to extract accuracy in numerical solutions. By exploiting superconvergence in the underlying numerical method, SIAC filtering can reduce oscillations, reduce errors, and increase convergence rates.

SIAC Applications

Flow visualization, shock detection, multi-resolution analysis, cut cells
