Hi Paul, I didn't understand what Justin meant. The first line in all output files looks like this: #std 4 12 12 12 64000 256000 .2165378385933E+03 5000 2 4 XU Thanks Joerg.
Hi Joerg,
Did you try Justin's suggestion of looking at your header? It probably already is 32-bit ? (This would normally be the case.)
Perhaps the output data is corrupted, e.g., nans or whatever...?

p63 is set to zero and it still does not work

It looks like setting p63=0 should take care of that...

Hi Paul,
how can I set up the single precision output?
best regards, Joerg.
Hi Joerg, Normally the output is indeed in single precision. It's not clear to me the double-precision + visit is working - but I've been a bit out of the loop on this. Paul On Wed, 20 Mar 2013, [email protected] wrote:
Hi Neks,
I am facing problems with the visualization in visit. The output of the three scalar fields uzt, epst, epsv is done is seen in the following line from my usr file.
Here, I wrote the data into four files (see further below). I also attach the visit script
!-------usr file------------------------------------------------- tiny=1.e-16 do i=1,n epst(i)=log(epst(i)+tiny) epsv(i)=log(epsv(i)+tiny) enddo
!-------No pressure field, no scalar output ifpo=.false. ifto=.false.
call outpost2( uzt,epst,epsv,pr,t,0,'eps')
ifpo=.true. ifto=.true.
!-------Visit script------------------------------------------------ NEK5000 version: 1.0 filetemplate: epsG1_64%d.f%05d firsttimestep: 1 numtimesteps: 1
!-------the four files that have to be load into visit and which make up one snapshot-------------- -rw-r--r-- 1 josc1234 linux 2657536136 27. Feb 08:03 epsG1_640.f00001 -rw-r--r-- 1 josc1234 linux 2657536136 27. Feb 08:09 epsG1_641.f00001 -rw-r--r-- 1 josc1234 linux 2657536136 27.

!-------This is the error message in visit--------------------------------------- The compute engine running on makalu51.rz.tu-ilmenau.de has exited abnormally.
Shortly thereafter, the following occured...
The Pseudocolor plot of "y_velocity" for the file "/usr/wrk/people4/josc1234/nek5_visit/r095_Lx1_12_Ra1e8/vis.nek5000" could not be generated by the compute engine on host "localhost".
My questions:
Could it be that the graphics output should be in single precision? I saw that the people at KTH did have similar trouble. If yes, how can I switch to single precision in the usr file output? For smaller grid it worked.
Thanks in advance, Joerg.
