Hi everyone!

Tke residual looks like in the image. It repeats continuously. Forces and force coefficients are almost stable after the 1000th iteration. I don't know why this happening. Is it enough small to ignore? If not, do you have any recommendations to decrease it more? Thanks so much in advance.

A very fine mesh with trimmed cell mesh.
Not a very complicated geometry.
Single inlet and outlet with 30 m/s velocity of air.
It's a rear wing geometry with a 1:2 scale.
Trailing edges for each element are not less than 1mm.
