Abstract

High-order CFD is gathering a broadening interest as a future industrial tool, one such approach is Flux Reconstruction (FR). However, to displace current, lower order, methods FR will likely have to be applied to stretched and warped meshes through the need to mesh complex geometries. The analytical and numerical behaviour of FR on deformed meshes is therefore carried out for both 1. D linear advection and the 2. D Euler equation. By direct comparison with Finite Difference (FD) and Finite Volume (FV) schemes widely used in industry it it shown that FR has increased wave propagating ability on warped and stretched meshes due to increase resilience to mesh deformation. Lastly the importance of a Jacobian order consistent with the underlying scheme order is shown via a degradation of FR order on highly warped meshes.
