Wall Motion

 

If [Translation] is selected, set the moving speed of the wall.

The velocity component in the direction parallel to the wall face is applied to the flow velocity on the wall.

The velocity component in the normal direction is ignored.

 

If [Rotation] is selected, set the rotation axis and then the rotational angular velocity of the wall.

Velocity

 

If [Translation] is selected, set the velocity components.

 

Angular velocity

If [Rotation] is selected, set the rotational angular velocities.

Vector of Rotation Axis

If [Rotation] is selected, set the vector of the rotation axis.

Coordinate of Rotation Axis

 

If [Rotation] is selected, set the coordinate of the rotation axis.
