Hello,
Diffusion of tracers = NO is not recommended as this step also deals with sources. However in your case the diffusion coefficient equal to 1.E-4 is certainly very small and I am not surprised that it makes no difference. A numerically efficient diffusion is in the order of velocity*(mesh size).
With best regards,
