Description

Adds five cards to the Featured Simulations grid on the landing page.

Aerodynamics (Ehsan Roohi's 2D immersed-boundary runs on the UMass Amherst Unity cluster, 32 MPI ranks, CPU):

Card Video Physics Grid
Mach 2.7 flow over a cylinder https://www.youtube.com/watch?v=9LhtzL6SqUg Euler, IB 1980 x 1800
Mach 2.7 flow over an ellipse https://www.youtube.com/watch?v=PlmuY2kAdvs Euler, IB 990 x 900
Mach 3 diamond airfoil at 40° AoA https://www.youtube.com/watch?v=rFL1HMOHX3U viscous, Re = 10^4, no-slip IB 2970 x 2700

Case files, render scripts, and checksums: https://github.com/Ehsan-Roohi/ShockVortexML/releases/tag/cfd-showcase-2026-09. Walltimes for these three are estimates (marked ~); the run archive does not record them.

Aerodynamics: Flapping wing wake (Q-criterion), https://www.youtube.com/watch?v=NXjkZB101Sk. Flapping plate at St = 0.3, roll 30°, pitch 20°, moving IB, 143.6M cells on 128 Frontier ranks (NSF ST-POD campaign). Walltime is an estimate.

Rockets & jets: Starship plume vortex structures, https://www.youtube.com/watch?v=uHEovMXASnI. CSCS/NVIDIA lambda-2 fly-in of the same Mach 12 Super Heavy run already on the page; card metadata copied from that entry.

Stills are frames from the videos (cyl.jpg, ell.jpg, dia.jpg, flap.jpg, ss2.jpg), 200-400 KB each.

Type of change

  • Documentation / website only

How Has This Been Tested?

Rendered docs/index.html locally with headless Chrome; all five cards appear in their groups with working YouTube links and images.

Mach 2.7 cylinder, Mach 2.7 ellipse, and Mach 3 diamond airfoil at
40 deg AoA, simulated by Ehsan Roohi on UMass Unity. Videos are on the
MFlowCode YouTube channel; stills extracted from the late-time frames.
