Hi Foamers,

I'm currently working on a modeling problem of air pollution and I have some difficulty to define the BC of a passif scalar ( concentration of polluant ).
I have four quantities on my 0 directory : velocity U, temperature T, pressure p and the passif scalar C. For the first three quantities, I have defined my BC like this : I employ Slip condition at the Top and Bottom walls and periodic condition in the x- and y-direction. For this three quantities everything is ok but for the four one I would to have this BC : The inflow condition for the scalar field is a constant concentration distribution Csource ; which is non-zero at the position of the line source(s) and zero everywhere else (a Gaussian distribution).
I have no idea how can I define this, can you please help me ?
Thank you.

PS : you can also take a look at the attached files to understand what I have done for U, T and p.
