Hi there Star CD Experts, can somebody tell me what the units of Scalar Flux if I pick CO as the scalar are, I can choose between fixed % and Flux what is the difference here?

Thanks in Advance for any help given

Scalar flux is in kg/s/m^2. Fixed concentration values is in mass fractions mf1 + mf2 +.... = 1. The difference between the two is like that of a fixed temperature wall against a fixed heat (W/m^2=J/s/m^2) wall.
