Recording and playing a Multipactor video

Creating a Multipactor video configuration

It is possible to create as many Multipactor videos as needed in a Multipactor Configuration. This way, you can record different videos for the same Multipactor configuration parameters. For example, you can choose a different region for the video. In order to create a new Multipactor video configuration, right-click on the Multipactor Configuration tree item and select Add Multipactor Video Configuration option as is shown below

A new Multipactor video configuration item will appear in the tree in the framework of the Multipactor Configuration.

Setting Multipactor video configuration parameters

Multipactor video configuration parameters are set from its corresponding window, which can be opened from Multipactor video configuration tree item by double clicking on it or using Open Video Configuration right-click option. 

Video Configuration

The video Configuration window is the following

 

 

Video for element / region

Here, the region in which the video is going to be recorded is selected

Input Power (W) Sets the input power for this specific video recording.
Number of Frames / period Specifies the frame rate of the recording. The higher the smoother the animation, but bigger video sizes will be generated.
Start time (ns) Sets the initial time for video recording.
End time (ns) Sets the maximum time for video recording.

Other parameters are taken from the current configuration, such as SEY definition, number of electrons, multipactor criterion etc.

Running a Multipactor video configuration

In order to start a simulation, you can:

If there is a video of a previous simulation, it will be deleted. The progress of the simulation can be followed in the info tab of the Main window.

Once the simulation is finished, the recorded video will open immediately with the Paraview, which allows for 3D rotations, perspective customization and zoom on the saved animations. It also allows for exporting the animation to common video formats, such as .avi format. For a more detail explanation on the visualization of the recorded video see Running Multipactor video tutorial section.

It is possible to play an existing video from the Movie tree item:
