[Nek5000-users] Restart problem

Hi Adam,

Have you tried the full restart option described in email

https://lists.mcs.anl.gov/mailman/htdig/nek5000-users/2010-August/000900.html

There was an earlier email about some problems with it -- I can check it once I came back from travel.

Best.
Aleks

Hi

I simulate jet in crossflow problem with nek5000 and I've got serius
problems with restarting the simulation. It causes strong spurious
velocity oscillation and I cannot get rid of them. I've implemented
restarting procedure described in prepost.f, but it doesn't help much.
Playing with file format (parameters p66, p67) and projection (p94, p95)
I can only decrease oscillations amplitude, but they are still there.
Surprisingly saving output files in double precision (p63=8) makes
everything worse. Has anybody got similar problems?
Best regards

Adam
