I study a two-dimensional simulation field with a SAS model in three different grids(the same grid with different domain size) and the results obtained in the fluent are very noisy in space. You can see an example of static pressure on one of the tubes and noise. I also get this noise at mean velocity magnitude along vertical lines in the flow domain.
This noise is also obtained in both average results in time and in momentary results.
I can not undestand the reason for this noisy results, it seems to me not physical.

I would be happy to know if anyone encountered such a thing and / or know how to solve it.
Thank you,
Shay
