Dear All,

I am fairly new to Fluent and UDF, therefore i would like to request some help on the following matter.

I intend to perform a simulation on a 2D airfoil. The airfoil will remain stationary until the solution approaches convergence. After that it should update the angle of attack by 1 degree every, let's say t = c/U, where c is the chord length and U the freestream velocity. The range of angles of attack would be from -180 to 180 degrees. However it is ok for each simulation to go from 0 until the extreme angle.

I have tried to create a '' for loop'' however it seems that something like that doesn't work.
Also regarding the rotation function: can i simply use axis rotation equations?
x'=x\cos \theta +y\sin \theta
y'=-x\sin \theta +y\cos \theta .}

These also didn't seem to work, but i'm guessing it's more of a coding issue.

Thank you in advance for all the help on the matter.

Best regards
