[Nek5000-users] Error when running the vortex problem

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

Hi, Stefan.
Thanks for the reply.

I double-checked the code and made sure I didn't change anything.  I found the error happens in the file "nek/ic.f" (line 2223). Please see the following.

if (indx2(hdr,132,'#std',4).eq.1) then
          call parse_std_hdr(hdr)
      else
         if (nid.eq.0) write(6,80) hdr
         if (nid.eq.0) write(6,80) 'NONSTD HDR, parse_hdr, abort.'
  80     format(a132)
         call exitt
endif

I looks like the code cannot find the keyword "#std" from the header. I read the file header shown in the following.
    140   8   8   8 5.0101000E+0250101 U P                             4 NELT,NX,N

The header does not contain the keyword... I guess that is the error reason.

Hi Dong,

It works for me. Did you change anything?
