Dear all,

I have a question about the units of implemented scalars. I have scalars for which I have to define a constant value at boundaries. Fluent solves the scalars in an equation that includes the density:

http://aerojet.engr.ucdavis.edu/flue....htm#eq-uds-1a

If you enter the boundary condition of a scalar as a "constant value", do you then specify the value in concentration "mol/m^3" or should you give the value in concentration times density "mol/m^3 * kg/m^3".

Easier put: should I multiply the concentration times the density at the Boundary condition?

Thank you very much in advance,
Kind regards
