Question Dynamic Domain

ral007 is on a distinguished road
Does anyone know how to set up a dynamic domain with moving mesh option? I have a trajectory profile (position, velocity, and coordinate transformation coefficients) that describe kinematics of a rigid body.
I set up a profile with position and velocity and FLUENT seems to follow that trajectory. Now I need to change the orientation (or attitude) of the rigid body by incorporation of coordinate transformation matrix. The coefficients vary as function of time. So what would be the best way to implement this?...
From the coordinate transformation matrix, I can obtain theta,phi,psi (directional angles). If I input the angles into the profile, ( as theta_x,theta_y,theta_z), will FLUENT know how to orient the rigid body?... What is the unit FLUENT expects? Degrees of Radians?...
