Reply To: Velocity based error in secondary lattice
Hey Julius,
I can’t reproduce your errors. Please make sure to understand the return values of our cell objects: The distribution functions we save in the data structure are actually f* = f – weight, so that the sum of f* = rho – 1, because the sum of the weights equals to 1. We apply the same shift to all the equilibrium distributions.
See Section V in https://journals.aps.org/pre/abstract/10.1103/PhysRevE.48.4823 for some more information on this topic.
Cheers,
Max
