Fig. 3From: Compact higher-order gas-kinetic schemes with spectral-like resolution for compressible flow simulationsLimit resolution for linear wave: Results of WENO-7th scheme with linear reconstruction and GKS flux, linear compact 6th-order and 8th-order schemes on the meshes with Δx=1/2 and Δx=1/4 at t=1. Since there are only two points for each wavelength on the left figure, the real "exact" solution should be averaged over half wave length as wellBack to article page
