Subject: Re: [Nek5000-users] Maximum number of history points using hpts()
I'm executing 9 times nek5000 to call hpts (using different
case.his files containing each 39960 points, using a shell script)
because I need When I'm using 359640=9*39660 points
This works perfectly fine. However when I'm trying to use a
single file in order to execute nek5000 once, it gives the
following error following error when the number of points is equal
to 359640 :
dump history points
reading history points
found 359640 points
APPLICATION TERMINATED WITH THE EXIT STRING: Segmentation fault
(signal 11)
I guess I'm encountering some memory problems..
Best regards,
Arnold

Subject: Re: [Nek5000-users] Maximum number of history points using hpts()
Hello Pierre,
In my case my case.his file contains 39960 points and lhis=39961,
however when I increased the first value and the lhis variable
accordingly it doesn't work anymore. Is there something I'm
missing?
Best,
Arnold

Hi

You can set it in the SIZE file:
param(lhis=100) ! # of pts a proc reads from hpts.in
! Note: lhis*np > npoints in
hpts.in

Hi Neks,
I was wondering if there is any maximum number of history points
one should put in the case.his file. If someone could help me
regarding that topic, I haven't found any information yet.
Thank you for your time,
Best,
Arnold
