[Nek5000-users] Initialise with random noise

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

Hi again Nek's,

I am working on the simple pipe flow as well, and I have a question
regarding the initialisation of the perturbation mode. I initialise my
perturbation with call random_number(vxp) call random_number(vyp) and call
random_number(vzp) and run the calculation on 4 processors for validation
and tests purposes. The domain is divided in four partitions in the
streamwise direction. Unfortunately, the call random_number repoduces four
times the same random field and as a consequence prescribes a streamwise
wavenumber which I'd like to get rid of. Any ideas on how to do that?

Regards,
JC
