Good day.

I'm currently studying the flow field around oscillating airfoils. I want to obtain the aerodynamic coefficients (drag, lift and moment) of the airfoils but these coefficients come with so much (numerical?) noise (see picture '1.png') and I still didn't find the root cause. The desired results should be something like picture '2.png'.

Notes:
- Data presented in '2.png' was filtered.
- Mesh quality is adequate.
- Y_plus parameter is correctly adjusted.
- Remeshing is activated.
- Time step seems to not have a clear influence.

EDIT 1:
- The root cause seems to be related to parallel computation.
