Running Multipactor video

Alternatively to a Multipactor analysis, it is possible to record a video of the electrons moving inside the 3D structure for a particular input power.

In order to set the Multipactor video parameters, you must

 Video Multipactor configuration window will be opened.



  1. Video for element / region : RectangularRegion  1 
  2. Input Power (W): 10000
  3. Number of Frames / period : 15
  4. Start time (ns): 0
  5. End time (ns): 20

The remaining parameters, such as SEY properties, number of initial electrons, multipactor criterion, etc. are defined in the  Configuration window.

Press Run button and the video generation will start. The video is saved inside the solution and, as in any other configuration, if the video configuration parameters are modified, the existing video will be erased.

When the simulation is finished, the video is automatically open with Paraview. 3D rotations, perspective customization and zoom are allowed on recorded animations. Play, pause, forward and backward buttons can be found on top. Animation parameters can be changed in the Animation View panel (View -> Animation View). Concretely, the video duration can be changed in the Duration textbox.

 Video can be exported using File -> Save Animation... The video size, duration and format can be chosen.
