UDF for Gyroscopic effect in a boat
 
Hi,
I would evaluate the gyroscopic effect on board. So I need to write an UDF that depend by positioni, angular velocity and angular acceleration. I see that in DEFINE_SDOF_PROPERTIES there is DT_THETA (dt) and DT_OMEGA_CG(dt). Is there also something like this for the angular acceleration? Something like an DT_ALPHA_CG?
Many thanks
Filippo
