Our research team has developed a novel approach to performance modeling. In particular, FLOPs and runtime are not necessarily complete performance indicators; as they ignore solution accuracy. The Time-Accuracy-Size (TAS) spectrum provides a holistic performance analysis appropriate for comparing different algorithms (Chang et. al.).
DG methods are able to take advantage of unstructured and non-conforming meshes. Below is a aritifical sphere packed porous domain, and a cross section of the unstructured mesh.
