[Nek5000-users] How to calculate Nusselt number in RB convection case

[nek5000-users at lists.mcs.anl.gov]

Hi Nek,
How should I calculate the Nusselt number(the average heat flux over the boundary) on the hot or cold wall of a 2D RB convection case? Nu=-Integral(tempy),that tempy means the partial difference of temprature in y direction, and Integral means the integral of tempy from x=0 to x=1. Is there any functions can realize that calculation? Thanks.

Kind regards
B.L.Xu
