[Nek5000-users] First Visit file

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

Hi Everyone,

I think the issue is the first line of the header.  It needs to be
"NEK5000", not "NEK3D".  It looks like the parsing of the header looks for
the form "TAG VALUE".  The exception is the first line, which is "NEK5000".
 So it tried to read NEK3D as a tag and then ate the filetemplate as the tag
"NEK3D"s value.

When I switched it to NEK5000, VisIt was able to read the file and make a
plot, no problem.

(Aleks: looks like we can read ASCII!  I wasn't sure myself ;)

Best,
Hank
