The Spinning feature in Flowvis allows the 3D geometry to keep spinning automatically once rotated in a given direction. This feature is disabled in Flowvis by default. If you want to enable the spinning feature, you can do this from the Preferences window. In the Flowvis menu bar open the Options menu and click on Preferences.
Open the Settings window

This opens a Settings window. Choose the Plot tab and check the box next to Allow spinning in 3D plot. Click on OK to enable the spinning feature.

Turn the spinning feature on/off
