NASA Mars Lander Simulation (IMAGE) DOE/Oak Ridge National Laboratory Caption Instantaneous solution quantities shown for a static Mach 1.4 solution on a mesh consisting of 33 billion elements using 33,880 GPUs, or 90% of Frontier. From left to right, contours show the mass fractions of the hydroxyl radical and H₂O, the temperature in Kelvin, and the local Mach number.
