[Nek5000-users] line integral: 1d average

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

Hello Neks

It is clear to me how to compute the volume and area integrals in Nek by 
reading the previous posts. However I could not find the proper 
implementation steps for line integral for doing 1d averages (i.e. 
extracting a 2d profile from a 3d field). In particular I would like to 
find the average along z-axis (yielding  ua = <u>_z, where ua( lx1, ly1, 
lelx*lely) if I am not mistaken).

I would appreciate if you could help me on that and guide me to the 
right direction.

Regards,
Hesam
