Hello fellow Code_Saturne users.
I am running a steady state simulation with rough walls and would like to compare it to smooth walls. For my rough walls, I believe i Have met convergence despite what seems to look like a noisy signal. Is there any way to alleviate the noise, maybe by constructing some sort of mean field. Or would maybe running a unsteady simulation be better?
I have attached the velocity field below.

Hello,
I think that you can use an octave or python script to calculate an average value after convergence is reached.

Re: Comparing smooth and rough walls
Thank you for the reply Luciano. I am currently trying to see if I can get an average value through the software 'paraview'.
If this isn't possible I will try another method.

Hello,
You can also construct a mean field using time averages in Code_Saturne.
You can activate those directly from the GUI.

Hello,
In paraview you can apply the "Temporal Statistics" filter. it will compute the average, the max and min values or use the time averages in Code_Saturne as Yvan mention.

Re: Comparing smooth and rough walls
Thank you for the response I will try these techniques out in Code_Saturne and Paraview respectively.
