Hello,

I would like to run a simple transport problem in a tube with a mixture containing part Gas A and part Gas B. I need to set the diffusivities. My question is: is the "Material Mass Diffusivity" of the background gas to be set in the binary properties a mixture-diffusivity (i.e. binary or Dab) or a self-diffusivity (Daa*) coefficient? Same goes for the "Scalar Mass Diffusivity". Finally, is the "Schmidt Number" in the binary properties to be calculated with a binary diffusivity or a self-diffusivity, and with a self-density?

Thanks for your help

-Dan
