There are two rotating zones, where the rudder zone is even part of the body zone. I have to alter the (local) coordinate system of the rudder zone during the rotation of the body zone. I'm not sure if this will work with the basic dynamic mesh UDF's,even dont know how to write the udf of the case.

I'm looking for your advice on UDF for dynamic meshing in aircraft during flight.

Yours sincerely,
