[Nek5000-users] post-processing using f0000 files

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

Not sure what you mean by “visit files”. They don’t exist. Nek produces so called field files. In fact there are multiple flavors (ASCII, binary, new binary). VisIt and Paraview have both implemented a reader to support these file formats. To read-in Nek field files you have to setup a so called meta-data file (created by the visnek script). 

You usr file implements z-averaging using gs. Note, this will only work for an extruded mesh. How did you generate your mesh?

Please use VisIt or our build-in interpolation tool (see Hemi example) to extract line data (e.g. velocity profile) out of the 3D volume field.

> <br style="font-size:12.8px" />Hi Nek,<br style="font-size:12.8px" /><br style="font-size:12.8px" />I am struggling with a problem in post-processing the files generated by<br style="font-size:12.8px" />calling avg_all (see<br style="font-size:12.8px" />https://lists.mcs.anl.gov/mailman/htdig/nek5000-users/2017-December/004832.html <https://lists.mcs.anl.gov/mailman/htdig/nek5000-users/2017-December/004832.html>).<br style="font-size:12.8px" />I used the attached usr files but obtained one visit file which seems not correct in terms of streamwise velocity number scale. So I got one question. <br style="font-size:12.8px" /><br style="font-size:12.8px" />Can you tell me how I can have a velocity profile file or rms file (e.g., txt or dat format) by using<br style="font-size:12.8px" />the avg*0.f000.. rms*0.f000...and rm2*0.f000, rather than a visit file. Please find attached usr file.
