7.6. Velocity Addition

The VELOCITY ADDITION capability is used to additively modify nodal velocities at a specified time.

BEGIN VELOCITY ADDITION
  BLOCK = <string list>block_names
  INCLUDE ALL BLOCKS
  APPLY AT TIME = <real>time
  COMPONENT = <string>X|Y|Z |
    DIRECTION = <string>defined_direction
  MAGNITUDE = <real>magnitude_of_velocity
