Dear Nek experts,

I would like to record different quantities such as the temperature or 
the velocity over the time.
I tried to use the subroutine "hpts()" in userchk. So I created a file 
hpts.in as said in 
http://www.mcs.anl.gov/~oanam/old_page/index.php/Data_processing_example.

The problem is that I had the error  "Cannot open history file in 
subroutine hpts()"

I also tried to rename my file to case.hpts_in but I still got the same 
error.

Does anyone have a suggestion ?

Thanks,
Samuel
