Dear all, I would like to impose a boundary mass flux in unit of kg/m^2/s in fluent. On the boundary, there are options to impose a species mass flux or mass fraction with values from 0 to1. This is obvious not applicable in my case. I also saw some suggestions to impose source term in the cells adjacent to the boundary. But the source term is in unit of kg/m^3/s. In fact, according the governing equation, the divergence of the boundary flux is the source term. I'm struggling to figure it out. Can anyone give me some suggestions or guidance? Thanks.
