Stream visualization

0 votes

Hi,

I am modeling 2D NS flow around a cycinder based off the fenics tutorial section 3.4 code and would like to achieve something similar to this karmen vortex visualization found on youtube:

At first I assumed the movie graphic was a velocity plot and set up the BCs accordingly (2 streams coming out of a wall on the left), but doing so revealed that the movie graphic was probably not a velocity plot (which makes a lot of sense in retrospect). Rather it seems part of the inflow is colored for visualization.

Anyone know how this might be done?

Thanks in advance.

Try a one way coupling of the NS equations to an advection equation in which the velocity of the tracer distribution comes from the NS solution.
