[Nek5000-users] Derivatives problem

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

Hi JP,

without context or magnitude, it's very difficult to tell if there is actually a problem
with that figure...  Do the color fluctuations represent 10^-15?  or 10^3 ?

With respect to what?

What were the initial conditions?

What is the quantity being plotted?  What is the scale of the color range?
etc.

If you can provide more information we might be able to help.

Best, Paul

Dear All,

Has anyone ever encountered this problem (or has any idea what might be causing this) when using derivatives: (see link to picture)

Regards,
JP
