A New Class of High-Order Energy Stable Flux Reconstruction Schemes
TL;DR: It has been proved (for one-dimensional linear advection) that the spectral difference method is stable for all orders of accuracy in a norm of Sobolev type, provided that the interior flux collocation points are located at zeros of the corresponding Legendre polynomials.
Journal ArticleDOI
Insights from von Neumann analysis of high-order flux reconstruction schemes
TL;DR: In the present study one-dimensional (1D) von Neumann analysis is employed to elucidate how various important properties vary across the full range of VCJH schemes, as are the magnitudes of explicit time-step limits.
Journal ArticleDOI
A New Class of High-Order Energy Stable Flux Reconstruction Schemes for Triangular Elements
TL;DR: A new class of energy stable FR schemes for triangular elements is developed, parameterized by a single scalar quantity, which can be adjusted to provide an infinite range of linearly stable high-order methods on triangular elements.
Journal ArticleDOI
On the Non-linear Stability of Flux Reconstruction Schemes
TL;DR: Non-linear stability properties of FR schemes are elucidated via analysis of linearly stable VCJH schemes, and it is shown that the location of the solution points will have a significant effect on non- linear stability.
