[Nek5000-users] Error when loading file

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

Hi Johan,


There's also an example in navier5.f in the subroutine autoaverager().


Usage is (say):


ls -C1 case0.f* > list.in


then add this to a blank .usr file and run it


c-----------------------------------------------------------------------

      subroutine usrdat2  ! This routine to modify mesh coordinates

      include 'SIZE'

      include 'TOTAL'

      character*127 fname127


      call blank(fname127,127)


      fname127='list.in'

      call auto_averager(fname127) ! simple average of files

      call outpost(vx,vy,vz,pr,t,'   ')

      call exitti('quit after autoaverager$',nelv)


      return

      end

c-----------------------------------------------------------------------



Paul

load_fld() expects a character*132 on input!

Cheers,
