I am having a hard time to find out how to input mass flux of a species in fluent, some people told me to write UDF, then I already wrote UDF for mass flux of that species (Define_Profile(mass_y_flux..)), but I am curious that, which boundary condition should I use for the boundary that I need to input species mass flux ?
