Mathias, thanks.rnOne more question, please:) I have detected, that for low kinematic viscosity values (~10^(-7) – 10^(-9)) one needs to make very-very small grids than for biger viscosity (~10^(-3) – 10^(-5)). I want to know is there a exact relation between viscosity value and latticeL value. My suggestion is that If one reduces viscosity value by 3 orders one has to reduce latticeL value by 3 orders too…
