How can I visualize the direction (forward or backward) of the precessional modes in a rotor dynamic analysis?

In ANSYS 10.0 if you request both real and imaginary mode shapes to be written by the QRDAMP solver
with MODOPT,QRDAMP,Nmodes,FreqB,FreqE,ON, you can animate the whirling motion with the same animation
macro used to animate harmonic results, ANHARM. This is listed a Time-Harmonic ... in the animate pull-down
menu. A special purpose animation tool for rotordynamics will be created for 11.0.
