[Nek5000-users] Regarding spatial resolution

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

Hey Neks,

I have a very basic question about the spatial resolution of Nek5000.
Suppose my elements in the domain are squares of unit length. If my GLL
points used are 17 (or order of the polynomial used is 16), what is the
least spatial length resolved by the code? As an approximate, can one use
1/17 units? Is there a way to calculate this least spatial length being
resolved?

Thanks,
Saikat
