[Nek5000-users] Setics subroutine in load_fld

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

Hi Navrose,

I do not know if there is any better method, because I would do it probably
the same way. Another way-- you can probably define another set of routine
say load_fld_pert(), with modified setics and RESTART file, but probably it
is as good as using opcopy().
