Navier–Stokes equation (2D incompressible), solved live numerically on a discrete grid ρ (∂u/∂t + u·∇u) = −∇p + μ Δu + f, ∇·u = 0 The ink (the white stuff on the left) is added so you can see the motion of the fluid.

Nice live visualization of the equations! Here’s a real-world laminar → turbulent transition in the Isar Canal (single frame vs. average from a 4K video).

The contest/prize is rigged though because nature and reality is not smooth. Any thoughts on that?

Where is cascade to larger scales? 2D turbulence is very different from 3D turbulence. The movie says nothing about the correctness of the simulation

Thats interesting as i dont see the way you designed said grid. I happen to know the only determanistic grid that can do this because i built it....the question then becomes why...

Look at all the ways the 49ers used TE/FB (U) motion to run the football last night. -balanced formation. U motion to run mid zone weak with an insert -Wing formation with U motion to run mid zone weak with a Y slide to block the DE -Wing formation, shift to balanced, U motion into I think Duo with TE going thru and U on DE -balanced formation. U motion to run Duo again -balanced formation. Y motion to run toss crack -shift into wing, U motion into strong toss -balanced formation. U motion into split zone (This one doesn't look right. Curious if this is correct) -Balanced formation. U motion to run something blocked like Duo (I think) but Y is coming from the other side to insert. U on the DE

You people only like the Wii U as well because you guys don't like the Switch 1 and Switch 2. If you guys actually were around the era of the Wii U and didn't have nostalgia glasses on, you guys can clearly see how bad the console was. Stop glazing the Wii U. It's performative.
