Angular velocities during impacts


Updated by Altair Forum User
I need to determine the angular acceleration and angular velocity of an object after impact at a certain timestep.
I am trying to get the results using anim/vect option. But the velocities shown are zero, which is impossible.
How do I determine the angular velocity and angular acceleration?

/ANIM/VECT/VEL and /ANIM/VECT/ACC are the keywords to be used in the engine file to extract the velocity and acceleration .
How did you impose this load on the model?.Can you specify the boundary conditions applied
Could you tell us on what elements you are checking angular velocity & acceleration?(1D,2D or 3D)
