Field	Contents	SI Unit Example
`ID`	If `STYP` = 1 Part set identifier If `STYP` = 2 Part identifier If `STYP` = 3 Node set identifier (Integer)
`STYP`	Type of identifier to apply the initial velocities. = 1 (Default) `ID` is a Part set identifier = 2 `ID` is a Part identifier = 3 `ID` is a Node set identifier (Integer)
`OMEGA`	Axial rotational velocity (Real)	$[\frac{rad}{s}]$
`VX`, `VY`, `VZ`	Translational velocity (Real)	$[\frac{m}{s}]$
`XC`, `YC`, `ZC`	Position of the rotational axis (Real)	$[m]$
`NX`, `NY`, `NZ`	Direction cosines for the rotational axis (Real)
`IRIGID`	Initial velocity for PART_INERTIA and CONSTRAINED_NODAL_RIGID_BODY_INERTIA = 0 Initial velocity is defined in PART_INERTIA and CONSTRAINED_NODAL_RIGID_BODY_INERTIA = 1 Initial velocity is defined in *INITIAL_VELOCITY_GENERATION. (Integer)
