An animation of swirl=0.07, viscosity=.0001 simulation. From t=47.0 to t=49.0, with Δt=0.02. The partially transparent green isosurface is dimensionless pressure of -1.0. The red isosurface is dimensionless pressure of -2.0. The blue shows a square enclosing -0.2<x<0.2 and -0.2<y<0.2 at the lower boundary. |
