Bumpy force plot?

Hi, I was wondering how to get a smooth force plot instead of these bumpy force plots like this? -

Thank you for your time and help,

Hello Frank,

For me, the force plots look okay, and as long as the convergence is good I would not look too close to the beginning of the simulation. Especially for wing simulations, you might have some separations which have to stabilize throughout the iterations. Also, you will have transient effects from for example the wing tip vortex, which will result in oscillating outputs.
Therefore to get more representative results if you just take the average of the last n-hundred iterations. (Last 300 hundred for your case might be appropiate)
