[Nek5000-users] Load_fld() without restart

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

Hi Holly,

If you wanted to load a .fld file without copying over your variables, you
could do something like

! Create temporary storage
real tmp1(lx1*ly1*lz1*lelv), tmp2(lx1*ly1*lz1*lelv), ...

! Copy simulation fields to temporary variables
call copy(tmp1,vx,nx1*ny1*nz1*nelv)
...

! Load field file and do whatever work you want to do with it

! Copy simulation fields back to nek variables
call copy(vx,tmp1,nx1*ny1*nz1*nelv)


You should be able to use some of the Nek scratch arrays to store your
temporary variables (instead of taking up more memory with the explicit
declaration), but I'm not sure at the moment which scratch arrays
load_fld() uses.
