Reply To: *INITIAL_VELOCITY_GENERATION_START_TIME

Hi, 

It appears the only issue arises from the usage of *INITIAL_VELOCITY_GENERATION_START_TIME in conjunction with *INITIAL_VELOCITY_RIGID_BODY.

*INITIAL_VELOCITY_RIGID_BODY is incompatible with *INITIAL_VELOCITY_GENERATION_START_TIME. Instead, you should use *INITIAL_VELOCITY_GENERATION with PHASE=1, scoped to the rigid body. This allows you to define the velocity generation, and then apply *INITIAL_VELOCITY_GENERATION_START_TIME to introduce a delay before the velocity is activated.

For additional details, please refer to the *INITIAL_VELOCITY_GENERATION_START_TIME section in the LS-DYNA Manual, Volume 1.

Cheers, Ram
