Re: [Nek5000-users] Regarding spatial resolution
Hi Neks, Just following up on this question. Thank you. Saikat On Thu, Aug 23, 2018 at 3:46 PM, Saikat Mukherjee <[email protected]> wrote:
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
Just check in eg matlab the spacing of the Legendre nodes in the element centre. If you want to be conservative, this is the largest grid spacing. On August 27, 2018 4:19:35 PM GMT+02:00, [email protected] wrote:
