Hi All,

I am analyzing natural convection inside 2D rectangular cavity in Comsol 4.0a.

I want to plot the graph of Nusselt number (Nu) along center/ vertical line.
Can anyone tell me how to get Nusselt No (Nu) from calculated results.


Thanks,
Safeer

Hi,

There is no Nusselt along the center line, i.e., in the air. The Nu is on the boundaries. Read about the Nu number.
