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

High-Order Overset Flux Reconstruction Method for Dynamic Moving Grids

“…Overset approaches were not developed for finite element methods until 2010's (Massing et al, 2013). Galbraith et al developed the first high-order overset DG scheme (Galbraith et al, 2015). In their method the domain was decomposed into multiple overlapping structured meshes, where each mesh can utilize the approximation order independently.…”

“…Since the high-order DG methods were developed for overset unstructured grids, two main approaches are incorporated to handle data communication between the grids. One is a face-based interpolation approach developed in (Galbraith et al, 2015), and the other is an element-based interpolation approach developed in (Nastase et al, 2011;Brazell et al, 2016). Although DG methods often use "modes" of polynomials as the basis functions without explicitly defining physical points for the polynomials in a cell, above overset DG methods define a set of quadrature points at each receptor cell.…”
