Hello,

I am trying to calculate the Nusselt number in a rectangular enclosure in COMSOL, using the basic formula Nu=hL/k where h can be found from the heat flux,

please, can anyone help me to do it right?

Actually, I don't know how can I define this formula in derived value? which heat flux must be taken?

thank you for your help.
