Driven Cavity at different Re

The Lattice Boltzmann BGK (till Re=888) and MRT model (over Re=888)
at 130x130 (till Re=8888) and 200x200 lattice.
This model rocks :-)

 Re=161


 Re=444 (filename suggests 888)

 
Re=888 (filename suggests 444)

 Re=3552


 Re=8888 (development)


 Re=8888 (development 2)

 Re=8888

 Re=10000

    Nice looking plots. It's almost like isocontours of the streamfunction.
    Which technique did you use to make the images?

    Hi NickD,
    I use particles that are advected in the flow field and accumulate their colors in the color buffer. With some parameter tuning you can get images like above.)
    Yes, they somehow represent streamfunction of the solution,
