# Constant

Syntax

  Offset Velocity [{of} SpeciesName | {in} MaterialPhaseName | {ls} {a | b | c}] = Constant [Offset = offset1 offset2[ offset3] | Scale = scale | Surface = surface | Equations = Equations…]

Summary

  Offset VELOCITY by constant value on surfaces v’ = scale*v + <offset_x,offset_y,offset_z>. If a scale is provided, both the quantity and its flux are scaled accordingly.
