Analysis of Corona Results

In this tutorial the capabilities of SPARK3D GUI to handle and better analyze the Corona results are shown. As general features you can find that:

Corona configuration results window

Corona results can be consulted in run-time. For the particular example followed in the tutorial, lowpass_HFSS.spkx, Corona results window looks as follows during the simulation:

There are two tables and one graph that are refreshed as new results are obtained: 

  1. The left-side table contains the threshold breakdown power for each pressure point corresponding to a certain region. If both the high pressure analytical rule and the numeric simulation type (see Corona Analysis Manual for further explanation) have been selected for evaluation, the table will have three columns instead of two, where the last one corresponds to the analytical rule.

  2. In the graph is represented the Paschen curve corresponding to the data showed in the left-side table. If both the high pressure analytical rule and the numeric simulation type (see Corona Analysis Manual for further explanation) are enabled, there will be two curves, one corresponding to the numerical analysis and the other one to the analytical rule. 

    By right-clicking on the graph, you can save it in a .png file and its data, which corresponds to the left-side table, in .csv format, respectively.

  3. The upper table shows the minimum breakdown power in the whole pressure sweep for each region under study. During the simulation process, the word "Simulating" appears in the cell corresponding to the region which is being analyzed. Besides, through this table the user can handle the results shown both in the left-side table and the graph:

    • By left-clicking on a cell corresponding to a particular region both the graph and the left-side table update their values to the current element.
    • By left-clicking on the cell corresponding to the signal value, the whole row is selected and the graph shows together the Paschen curves of all the regions analyzed. With this information it is easy to recognize which is the most critical region for Corona discharge and the minimum breakdown power supported by the device.
