<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">Frequency of the average output is controlled by param 68.</p>
<p style="margin-top:0;margin-bottom:0">Default I believe is 500 if p68=0.</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">Note that if you output avg files every time step it will look just like</p>
<p style="margin-top:0;margin-bottom:0">a regular f0000 file because each avg file is just an average over the</p>
<p style="margin-top:0;margin-bottom:0">steps from the previous avg output step. So, in the case of p68=500,</p>
<p style="margin-top:0;margin-bottom:0">avgx0.f00001 would have the average for steps 1-500; ...02 would have</p>
<p style="margin-top:0;margin-bottom:0">501 to 1000; etc.</p>

<div>Dear Neks,</div>
<div><br>
</div>
<div>I'm running some cases of natural convection flows inside a box domain and I want to compute and visualize turbulent statistics of the velocity fields.</div>
<div><br>
</div>
<div>I tried this workflow:</div>
<div>- Call avg_all on every usrchk execution, thus I got a avg/rms/rm2-blah0.f* file for each iostep.</div>
<div>- Execute visnek for each series of *blah0.f* files</div>
<div>- Open the *.nek5000 files on paraview.<br>
</div>
<div><br>
</div>
<div>blah.nek5000 works fine, showing all fields on every timestep, but for the avg,rms and rm2 series I only a few timesteps 'frames' out of all the *blah0.f* files.<br>
</div>
<div><br>
</div>
<div><br>
</div>
<div>Last test I ran was:</div>
<div><br>
</div>
<div>p010 = 100 seconds</div>
<div>p015 = 50</div>
<div>p068 = 0</div>
<div><br>
</div>
<div>which outputted 200 *blah0.f* from where I got 200 timesteps frames for regular blah0.f* and only 4 timesteps for the avg_all fields.</div>
<div><br>
</div>
<div>I would like some advice on how to properly generate the avg_all files or the post-processing workflow requiered to get a 'smooth' visualizing of the statistics.<br>
</div>
<div><br>
</div>
<div><br>
</div>
<div>Regards,</div>
