Thanks,  Ravi,

I would try a Nek run with ASCII dump  (p66<0 in .rea) to check whether formatting of the files is an issue.

Hi Ravi,

What error are you getting?  It should not be the same error you reported earlier:

VisIt could not read from the file "C:\Users\s pendyala\AppData\Local\Programs\LLNL\VisIt 2.7.2\lowMach_test0.f00001.nek5000".

since you are presumably opening lowMach_test.nek5000 instead, right?

Aleks

I get error even now. I  modified the way you suggested, but still I get error. I typed 'visnek lowMach_test'. I get below message in my terminal.

Also one may need to correct for an endian by inserting the first line "endian big" or "endian little" in case of, e.g., files transfered from other systems

Total 10 file(s) are in the generated file lowMach_test.nek5000 ... Done!

But when I try to view the files

I get the error again.

Hi Ravi and Tanmoy,

Actually you need to provide a case name for visnek script since it creates the following template

    echo 'filetemplate:        '$base'%01d.f%05d'               >  $base.nek5000

Thus you should try

visnek lowMach_test

and not 'visnek lowMach_test0.f00001'

(ANother alternative, before running nek with scripts tools/scripts/nek*, delete 'rm SESSION.NAME<http://SESSION.NAME>' from them and just type visnek so it can look up for the case name in the SESSION.NAME<http://SESSION.NAME> file)

I have my nek5000 program on linux system. For post processing I take the data files on to my windows system where I have my VisIt tool. Is this problem for not being able to read the files. visnek also didn't help. I did this.  start VisIt and use File->Open AsŠ and then select Nek5000 reader as the reader to use to open the files. Thanks for your patience.

ERROR:

VisIt could not read from the file "C:\Users\s pendyala\AppData\Local\Programs\LLNL\VisIt 2.7.2\lowMach_test0.f00001.nek5000".

The generated error message was:

There was an error opening C:\Users\s pendyala\AppData\Local\Programs\LLNL\VisIt 2.7.2\lowMach_test0.f00001.nek5000. It may be an invalid file. VisIt tried using the following file format readers to open the file: Nek5000

The following error(s) may be helpful in identifying the problem:

When attempting to use "Nek", the file matched the general format expected by the reader but eventually encountered this error: "Could not open file C:\Users\s pendyala\AppData\Local\Programs\LLNL\VisIt 2.7.2\lowMach_test0.f000010.f00001, which should exist according to header file C:\Users\s pendyala\AppData\Local\Programs\LLNL\VisIt 2.7.2\lowMach_test0.f00001.nek5000.".

Hi Ravi,

try visnek <name of your fld file>
A <>.nek5000 file would be created. You would be able to read that from visit

Hi,

Create a separate file with ' .nek5000 ' has extension and write those lines in it and open it via Visit and It should work.

No. I didn't not get a clue of working with metadata file. I read about it. Couldn't figure out how to create this. Is a a separate file or set of commands?

Hi Ravi,

Did you create a metadata file ?? A meta data file is the one which helps you to open a *.fld or *.f00000 file in visit

It looks like this

NEK5000
version: 1.0
filetemplate: divpipe%01d.f%05d
firsttimestep: 1
numtimesteps: 09

Best regards,
Kamal
