Description

Current discretization for steady Navier-Stokes flow employs DG method only for viscous interface constraint. When the DG method is fully employed over all interior faces, the convergence rate becomes sub-optimal. The proper full-DG formulation for steady NS flow isn't figured out yet.

Research direction

Start by reviewing the current steady Navier–Stokes discretization and its existing DG treatment for viscous interface constraints. Done means establishing a full-DG formulation over all interior faces that avoids the reported sub-optimal convergence rate.
