[Nek5000-users] Visit reader for double precision f files

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

Hi Philip,

With regards to VisIt, I am happy to investigate.  IIRC, this issue came up
before and we decided that the reader did work.  (But possibly it slipped
off my queue and it doesn't work!!)

If you can make a file available to me (hchilds at lbl.gov), I can pursue.

With respect to the file format issue, someone else more knowledgable will
need to answer.

Best,
Hank
