Recording and playing a Corona video

Creating a Corona video configuration

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

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

Setting Corona video configuration parameters

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

Corona video configuration window

It looks like this

 The meaning of the different parameters is the following:

Video for element / region

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.

Pressure (mBar) Sets the pressure value for this specific video recording.
Number of Frames Specifies the frame rate of the recording. The higher, the smoother the animation, but bigger video sizes will be generated.
Accuracy Sets the level of accuracy that will be used in the electron density computation. The higher is this level, the more accurate, time and memory consuming is the computation.
Stop criterion

Sets the criterion used in the last frame of the video to stop the computation of the electron density:

  • If "Maximum electron density" is selected, the maximum value of the computed electron density in the last frame of the video will be approximately the value fixed by the user.
  • If "End time" is chosen, the electron density time evolution will be calculated till the time specified by the user.
Other parameters, such as gas type and temperature, are taken from the Corona configuration to which the current Corona video belongs (in terms of tree hierarchy).


Running a Corona 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 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 Corona video tutorial section.

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