LSTC HIII dummy models and adding initial velocities

Error.k · 2025-01-29T14:14:40Z

Hi, I'd like some advice regarding applying initial velocities to the LSTC rigid body models Usually, I'd just use *INITIAL_VELOCITY_GENERATION and assign an initial velocity to a group of deformable parts in a part set. However, in this model, there are many rigid bodies, discrete elements and joints. How would you go about adding an initial velocity to the whole dummy? I'd like to do a simple test where I add an initial velocity and have the dummy impact a stationary object, like a block or a cylinder. I know the alternative would be give the block an initial velocity, but I'm curios to see the body kinematics after the collision. Thanks!

Hmm yeah those plots aren’t what you should be getting. Did you try using the node set with the irigid settings I suggested?
