[Nek5000-users] History points

Hello Nek's,

I have a few questions on how to use the history points.
I have seen on the wiki the following stuff:
>
>
>     History points
>
> Specify grid points to monitor the specified variables in time. Example:
>
> ***** HISTORY AND INTEGRAL DATA *****
> 1    POINTS.  Var, Hcode, I, J, K, IEL
>              UV P    H    2  2  1  4
>

I bet Var stands for variable, but what do Hcode, I, J, K, and IEL stand 
for ?

Once you have specified the location of your history point, let's say a 
point on the centerline of a stenotic flow at whatever streamwise 
station, how do you get the data concerning this history point? Do you 
have to change anything else in the output specification section ? I 
have tried to add the wiki lines up there directly in my blah.rea but 
once I ran the code I did not get any new files other than the expected 
blah.fld's.

Regards,
Jean-Christophe
