Fig. 22From: An improved WENO-Z scheme with symmetry-preserving mappingThe density contours of isentropic vortex propagation at t = 1000. This figure is drawn with 9 density contours between 0.55 and 0.95. A uniform grid with 80 × 80 cells is used, \( \Delta x=\Delta y=\frac{1}{8} \). CFL = 0.5Back to article page
