Hello everyone!
I am generating a disturbance model for my aircraft to quantify the effect of asymmetries.
For this purpose i want to find the transient response of aircraft and rudder control surface if the aircraft is flying at a fixed sideslip angle. For this to happen, the aircraft along with rudder will be yawing about the center of gravity of aircraft in addition to the rudder rotation around rudder's hinge axis. Any suggestions on how this may be possible in fluent.
I know and i can simulate aircrafts yawing around center of gravity using sdof simulation and sdof udf.
I need help with rudder's rotation. How can i simulate rudder's rotation in addition to aircraft's rotation.

Your help will save me alot of R&D and reading time. Thank you
