    Click on the box next to Zero velocity in the field Type.

  4. Click on Apply to set the boundaries.

  5. Click on the box next to show in the dialog window.

    The velocity boundaries are displayed in the drawing. If you click on the box next to show all, the temperature boundaries are displayed as well.
