[Nek5000-users] DNS of turbChannel

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

The turbChannel example is using a high pass filter relaxation term as SGS. For a DNS just

- set lx1=8 and lxd=12 in SIZE
- generate a finer mesh with more elements using genbox (if you change the mesh make sure to delete the old amg files)
- set filtering=no in par

> Hello Paul,
> Thank you a lot for your explanation; it really helps. For now, I am using the most recent turChannel example of NEK5000 V.17. I successfully simulated a turbulent channel with a Retau of 180 using 1536 elements (I am aware of its a lot
>  of elements). The default settings were applied. I wonder is it in the .par file where you do the modification to convert it into DNS? Or somewhere else as well?
