Detailed Description

The ndg_moe_rossmanith class applies limiters to a dataset.

This is my attempt at implementation of DG limiter presented by Moe and Rossmanith for Warpxm

The paper is: A SIMPLE AND EFFECTIVE HIGH-ORDER SHOCK CAPTURING LIMITER FOR DISCONTINUOUS GALERKIN METHODS. SCOTT A. MOE, JAMES A. ROSSMANITH, DAVID C. SEAL. 2015. https://arxiv.org/abs/1507.03024
