  8. From the Source drop-down menu, select the vector field to be used for streamline creation (typically the velocity field).
    Note: You can also click Advanced Options to open the dialog which allows you to change a number of parameters that control how the streamlines are generated.

  10. Click Create Streamlines to create and view the streamlines.
