[COMSOL_Users] set wall to free stream boundary condition..

[Yolanda Lim]

I'm doing simulation of the heat transfer of Fuel Cell, I have an exhaust fan on the outlet and the inlet is the hole between the stacks, due to the thousand hole of it, i would like to draw a air hood for the inlet,but now i'm facing a problem which is how to set the hood wall to free stream boundary condition, so that it doesn't affect the result?

do you have a sketch? what do you mean "free stream boundary condition"? maybe this in german "freie konvektion"?
