Finite element discretizations of problems in computational physics often rely on adaptive
mesh refinement (AMR) to preferentially resolve regions containing important features …

In this paper, we present h-and hp-adaptive strategies suited for the discontinuous Galerkin
formulation of the compressible laminar and Reynolds-averaged Navier–Stokes equations …

Generating meshes with the right resolution is crucial for hybrid RANS/LES simulations of
high Reynolds number flow with complex physical phenomena and geometries. This makes …

High-order discontinuous Galerkin methods have become a popular technique in
computational fluid dynamics because their accuracy increases spectrally in smooth …

Mesh quality is critical for the numerical accuracy of CFD (Computational Fluid Dynamics).
Although various techniques have been developed to improve mesh applicability to complex …

We develop and analyze error estimators and mesh adaptation strategies within a
discontinuous Galerkin formulation. The basic idea of the study is to reduce the …

This paper proposes a face-area-weighted 'centroid'as a superior alternative to the
geometric centroid for defining a local origin in a cell-centered finite-volume method on …
