Re: [ESPResSo-users] LB + vtk file format

[Georg Rempfer]

I usually create videos using exactly the technique you describe. Here
are some examples by Owen Hickey and me:

As you can see in the last one, if you use a reasonably thermalized
LB, the individual frames are basically meaningless since everything
drowns in fluctuations.
