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

Optional unit identifier

(Integer, maximum 10 digits)

 

inivel_title

Initial velocity block title

(Character, maximum 100 characters)

fail_lad_SI_k or fail_johnson

VY

Y velocity

(Real)

fail_lad_SI_k or fail_johnson

VZ

Z velocity

(Integer)

 

skew_ID

Skew identifier

(Integer)

 

hmtoggle_plus1Comments
1.The grnd_ID input is obligatory. The initial velocities will only be applied to nodes belonging to a node group.
2.Unit of velocity in translation is fail_lad_SI_k. In rotation, then angle is in unit [rad] and thus the velocity is in unit symbol_Rad_s.
