pitch damping derivatives and forced oscillation technique
 
Hello everyone,


I am trying to predict the pitch damping derivatives of re-entry vehicle in the subsonic part of the descent.

By studying all over the internet, this is an unsteady problem that can be solved by performing a Sliding Mesh or a dynamic mesh simulation (forced oscillation technique)



I was wondering, however, it is possible to reach fair results with a Moving Reference Frame simulation, which is way less computationally expensive than the previous mentioned techniques.


Any thoughts would be appreciated.


Thanks a lot
