It is just fins and fluid channels. See attached picture. In the physical system it has a heat flux applied to the outside wall. I am modeling this via a cell register and a source term applied in the cell zone condtions dialog box. Now, when I get to boundary conditions for the fins there is a heat generation rate of 0 W\/m3 auto assigned to those same zones. Does one condition overwrite the other? Or would it be better to restrict the source term to the actual fluid cells and then put a heat generation term on the walls?
