Re: Diffusion with TRT collision operator

[tobit]

Thanks a lot, that solved my problem!
Funny enough I had already tried something similar: I simply swapped omegap and omegam but doing so I also changed the rest node relaxation rate and therefore I still had a similar problem.
So for the advection-diffusion equation the rest node is still relaxed with omegap but in this case omegap is calculated with the magic parameter whereas omegam is calculated with the LBM diffusion coefficient.
Thanks again!
