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.

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.
