Improved interpolation for viscous overset grids

A discontinuous Galerkin scheme for Chimera overset viscous meshes on curved geometries

“…The use of curved elements for a finite volume discretization was also explored by Noack and Belk in Ref. [23]. An additional advantage of the DG discretization in this regard is that the higher order accuracy permits the use of fewer cells compared to FV and FD schemes to capture a viscous boundary layer.…”
