[Nek5000-users] Flow Rate Oscillation on 16384 cores

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

Dear Philipp,

The slight flow rate variations are probably due to quick way we calculate
the flow rate.. this is calculated on custom files that contain data which
was converted from the original nek dumps.. the mesh spacing is not
constant in the y direction and probably causes some oscillations.. what I
cannot understand is how changing the number of cores affects this
oscillation so much in the region where more cores were used...

Regards,
JP
