[Nek5000-users] line integral: 1d average

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

Hi Justin

Thanks for your reply. Yes I have equal grid spacing in the z-dir. I 
guess you are referring to planar_average_s and planar_average_r,.... so 
I would appreciate it if you could share your modified version with me; 
that would save me some time.

Thanks
Hesam
