Fig. 19From: An improved WENO-Z scheme with symmetry-preserving mappingContour lines of density of the RTI problem at t = 1.95. This figure is drawn with 15 density contours between 0.9 and 2.3. A uniform grid with 120 × 480 cells is used, \( \Delta x=\Delta y=\frac{1}{480} \). CFL = 0.5Back to article page
