[Nek5000-users] Instantaneous velocity field

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

this is not really instantaneous data, but rather statistics. Then you 
would need to run some kind of averaging (in time, space etc.) and 
proper postprocessing afterwards, which strongly depends on the actual 
flow case. I am sure that there are people in this group that have done 
this type of analysis for a variety of flow cases/geometries.
