[Nek5000-users] computing grad(T) in NEK5000

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

Dear Paul,

I want to compute grad(Temp_field) for Rayleigh-Benard convection
simulation. I found two functions in navier1.f, "opgrad" and "opgradt" which
compute grad(scalar_field).

Which one of these functions should I use? Please help.

with regards,
Supriyo
