q86091483 is on a distinguished road
Dear all OpenFOAMers:
This is my first time to have a public thread in CFDonline.

It is known that most of the finite volume CFD with unstructured mesh, including OpenFOAM, possess 2-th order accuracy in space. However, for some applications, such as LES for turbulence combustion and acoustic instability, high order algorithm on unstructured mesh is needed.

So far, there're several in-house codes that use 3-th or 4-th DG (discontinuity method) to achieve higher space accuracy. These codes include AVBP ( and some other papers also shows that it's possible to implement high order DG method on unstructured mesh.

My questions:
1. Is it possible to implement DG-like method in OpenFOAM.
2. Whether the current system, ( I mean: interpolation->matrix solver) fits for the DG

I've been searching for this topic but it seems that there' little material on the internet. Looking forward for your opinion !

Have a look at HopeFOAM :

It provides DG formulation for OpenFOAM.
