Order of accuracy & Stability
Version 1.0.0 (11.4 KB) by
Manuel A. Diaz
This snippet shows how I examine the order of accuracy (OOA) and the numerical stability for a given numerical scheme.
In this snippet I examine the OOA and the stability for Lele's 6th-order numerical scheme [1] using a challeging stationary-wave problem proposed by Brady & Livescu (2019) [2] using the one-dimensional system of the wave equation.
