[Nek5000-users] Function to calculate volume intergral

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

  Hi,

     Is there a function one can use in Nek that computes volume 
integrals. I'd like to compute the Nusselt number for Rayleigh-Benard 
convection (=1 + <Vy*Temp>), where Vy is the vertical velocity and <> is 
the volume integral.

Thanks,
Mani
