Oh now I found it.∂u/∂t + (u . ∇)u - ν∇²u = -∇w + g is the convective form of
the incompressible Navier-Stokes equation
https://en.wikipedia.org/wiki/Navier%E2%80%93Stokes_equationsIt is interesting
that it is similar to the heat equation and the wave equation. -J.

have a formula The first part looks indeed more like a heat equation ∂u/∂t -
v∇²u = 0https://en.wikipedia.org/wiki/Heat_equationI would say it is a special
kind of heat equation.-J.-------- Original message --------From: Jochen Fromm

Nothing to do with nick, do we have a formula ∂u/∂t + (u . ∇)u - ν∇²u = -∇w + g
looks a bit like a wave equation ∂²u/∂²t - c²∇²u =
0https://en.wikipedia.org/wiki/Wave_equation...but it is not a second order
differential equation because it contains only a normal derivative like the
Schrödinger equation from Quantum
Mechanicshttps://en.wikipedia.org/wiki/Schr%C3%B6dinger_equationMaybe one of
our Mathematicians knows?-J.-------- Original message --------From: jon zingale
