In Post-Pro 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 the basic. Post-Pro automatically generates another frame displaying the 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 the initial state in the basic state. Sweeping is a type of animation composed of these frames: the frame displaying the initial field presentation will start the animation, the frame displaying the basic field presentation will end it.

To sweep a field presentation:

In the Main menu select View -> Windows -> Sweep. The following dialog will appear.

Navigation tab provides possibilities for managing and running the sweep:

Control buttons allow to launch or end the sweeping, run it forward or backward, move to the next or the previous frame.
Cycled checkbox allows to view the sweep in the loop.

Properties tab allows to set sweep properties.

Mode gives the choice between Linear, Sine and Cosine sweeping.
Number of steps - allows to set the number of steps, which will compose the whole animation.
Step delay - allows to set the time of representation of one step.

It is also possible to fast-launch Sweep with default parameters by right-clicking on the presentation in the Object Browser or in the viewer and selecting Sweep in the context menu.

Default parameters for Sweep can be set in the Main menu in File -> Preferences -> Post-Pro -> Sweep, Animation tab
