Sweeping

In VISU there is an option allowing to display pseudo-animation of a field presentation. For creation of this pseudo-animation you should take one field presentation generated on the base of ONE Time Step (For comparison, Animation  is generated on the base of ALL Time Steps of a field). The frame displaying this field presentation will be basic. VISU automatically generates another frame displaying initial field presentation, which is composed of cells with minimum acceptable values regarding the values applied to the cells of the basic presentation. It also automatically generates a user-defined number of frames (steps), which will display the process of transformation of the field presentation from initial state into basic state.  Sweeping is a type of animation composed of these frames: the frame displaying initial field presentation will start the animation, the frame displaying basic field presentation will end it.

To sweep a field presentation:

1. Create a field presentation.

2. Right-click on this presentation in the Object Browser or in the viewer.

3. From the pop-up menu select Sweep option.

4. Enjoy it.

In VISU sweeping is available only for Scalar Map, Iso Surfaces, Cut Planes and Deformed Shape presentations.

To set sweeping preferences:

In the main menu choose Preferences > Visu > Sweeping the following dialog box will appear:

Time step: time of representation of one step.

Number of cycles: defines the number of times this animation will be repeated.

Number of steps which will compose the whole animation.

These preferences will be saved for all SALOME sessions.
