CTRAN/W Boundery Conditions

Hi,

I'm curious about the difference in the boundary condition "Solute source concentration" and "Solute concentration". How does these work and in which situation does one apply the one or the other?

    Hello,

    The solute concentration boundary condition applies the specified concentration to the associated nodes, representing a concentration-type boundary condition.

    The solute source concentration boundary condition applies a mass flux to the associated nodes using the following equation:

    where C is the defined concentration and qw is the water flux entering the domain at those nodes. Thus, this boundary condition is a mass flux type of boundary.
