Help!! About distribution of h2 in the air

February 15, 2005, 16:44

Hi everyone,

I am modelling a case about the distribution of h2 in the air in a cubic. But h2 never goes upwards but downwards, there must be something wrong. I think the problems may exist in the settings of the panel "binary properties" under the folder "Thermophysical properties -> addtional scalars". Please tell me how to define the options about "diffusivity"

Many thanks!!

do you check your gravity direction?

yes, I checked the gravity direction, what else can lead to such a failure?
