Normal Velocity
The Normal Velocity adds a source at an exterior boundary defined by the inward normal velocity vn or alternatively given through a velocity v0:
Normal Velocity
Select a Type: Inward Velocity (the default) or Velocity.
•
For Inward Velocity enter the value of the Inward velocity vn (SI unit: m/s). Use a positive value for inward velocity or a negative value for outward velocity.
•
For Velocity enter values for the components of the Velocity v0 (SI unit: m/s).
