[Nek5000-users] Setics subroutine in load_fld

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

Many thanks Tanmoy.

So each time load_fld is called it will load the base
flow variables (I am carrying out computations for incompressible N-S
equations). What if I want to load the perturbations also from a different
file? One way that I see it is to use load_fld for the restart file for
perturbations, copy it in the perturbation variables (vxp, vyp, vzp, prp),
and then again use load_fld for the base flow file. Is there a direct or
better method for this?

Thank you.

Best wishes,
Navrose.
