[Nek5000-users] Total energy and wall gradients

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

Hi Nek's,

I am about to run a 3D-stenotic flow DNS, and I would like to compute 
the total energy in the computational domain. So far, I have only a 
routine for 2D (surf_int). Does such a 3D routine exists?
My second question concern the velocity gradient normal to the wall. Is 
there any way to output its value at various wall points for each time 
step? I was thinking ofadding a few lines to the hpts routine, but I am 
sure about what to write exactly. Could anyone give me a clue?

Sincerely,
JC
