[Nek5000-users] Restarting a Nek5000 job (Fault Tolerance study)

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

Hi,

p68 is for the frequency of the average_all routine, often used in
post-processing results.  If you just want .fld files for restarts, you can
change parameter 15 (IOSTEP).  This will then set Nek to dump out fld files
every X steps as set by this parameter.

hth,
Katherine
