How fast are most navier-stokes solvers today? Could they say, solve for the flow attributes around a fighter jet at subsonic speed with reasonable (but not perfect) accuracy, in real time?
is your family name Cho? are you Korean or Chinease?. I'm Korean. Anyway, glad to see you.
I think the speed of the solver depends on your system. When I tested the openflower under my personal linux system of patium3, it took 45min for an example in package. it was quite well performane
