/INIVEL

Block Format Keyword Defines initial velocity on a group of nodes.

Format

Field	Contents	SI Unit Example
`type`	Initial velocity type. TRA Translational material velocity. ROT Rotational material velocity. T+G Translational and grid material velocity (only used for ALE material). GRID Grid material velocity (only used for ALE material).
`inivel_ID`	Initial velocity block identifier. (Integer, maximum 10 digits)
`unit_ID`	Unit Identifier. (Integer, maximum 10 digits)
`inivel_title`	Initial velocity block title. (Character, maximum 100 characters)
`V`_X	X velocity. (Real)	$[\frac{m}{s}]$ or $[\frac{rad}{s}]$
`V`_Y	Y velocity. (Real)	$[\frac{m}{s}]$ or $[\frac{rad}{s}]$
`V`_Z	Z velocity. (Real)	$[\frac{m}{s}]$ or $[\frac{rad}{s}]$
`grnd_ID`	Node group on which specific initial velocities are applied. (Integer)
`skew_ID`	Skew identifier. (Integer)

The grnd_ID input is obligatory. The initial velocities will only be applied to nodes belonging to a node group.
Unit of velocity in translation is $[\frac{m}{s}]$ . In rotation, then angle is in unit $[rad]$ and thus the velocity is in unit $[\frac{rad}{s}]$ .
