[Nek5000-users] extracting data in a smaller computational domain and in a plane

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

Hi SL,

The easiest way for a profile is to do the Lineout in VisIt and choose 'curve' format in 'Set Save Options'.

More accurate way is to setup history/coordinate points in hpts.in file and call hpts routine from userchk which will also work for 2D plane points.

Subject: [Nek5000-users] extracting data in a smaller computational domain      and in a plane

Hi Neks,

I am trying to do some postprocessing of the Nek5000 results.

I have a 3D domain, however I will be interested in taking a smaller
piece of this domain. The idea is to generate a data base of snapshots
containing this smaller part of the domain. For example,

if my computational domain is x in (-15, 20), y in (-20, 20), z in(0,2)

I just want to take a data set of snapshots containing the velocity
fields in the locations:
   x in (-2, 5), y in (-5, 5), z in(0,2)

Is there any way to extract this data?

In addition, is there any way to extract the same data but in a 2d
plane? I mean:
   x in (-2, 5), y in (-5, 5), z=1

Thank you in advance.
Cheers
SL
