[Nek5000-users] boyd filtering in dyn. Smagorinsky model

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

Hello Neks,

In *turbChannel* example, explicit modal filtering has been used in the
dynamaic Smagorinsky case in the eddy_visc(eddif,e) routines.

  This routine calls the setup filtering routine
   *set_ds_filt(fh,fht,nt,diag,nx)*,  where coefficients for diag() are
defined manually.

  Cases for nt = nx1-1 and nt = nx1-2 are mentioned in the routines. I am
wondering if anybody        could tell me how to set up the routines for nt
= nx1-3 and nt = nx1-4, where nt is the filtered grids.


Thanks in advance,
Sincerely,
Tanmoy
