Great, Hank, thanks!

I'll adjust the script.

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

Hello, 

For some reason you have ASCII format which is usually triggered by param(66)<0 in .rea or an overwrite in .usr file with param(66)=0 instead of repo's param(66)=4 -- could you check you .usr file? 

Visit reader may not work with it since it's optimized to work with large datasets for which ASCII format is prohibitive.

Hi, 

I used a test case (10 dump files from test1.fld01 to test1.fld10) which 
head sections look like this (test1.fld01):

... 
------------------------------------------------------------------------ 

the test1.nek3d file obtained after running the script contains: 

------------------------------------------------------------------------ 
NEK3D 
filetemplate: test1.fld%02d 
firsttimestep: 1 
numtimesteps: 10 
meshcoords: 1 
------------------------------------------------------------------------ 

However Visit is unable to read it: 

------------------------------------------------------------------------ 
The file format reader issued the following error message, which may (or 
may not) be indicative of the problem: 

VisIt believes this is a "Nek" file. Further, the reader for this format 
believes this is a non-compliant file of this type. Its description of 
non-compliance is: "A tag called filetemplate: must be specified" 
------------------------------------------------------------------------ 

Thanks.
