Hi Antoine,

take please the UnitConverterFromResolutionAndLatticeVeLocity and set the lattice velocity to 0,1. In that case the converter will aoutomatically calculate the relaxation time by which the simulation runs stabely.
The relaxation times defines how far goes the population inside of one time step.
