11.5. Coupling

This menu allows the visualization of the coupling values between each source and receiver pair. As such, this submenu is only visible when a Coupling simulation has been executed.

The available options under this menu are the following:

  • Coupling Values: This options presents a table showing the coupling values for each source-receiver pair and each simulation frequency. The user can select the speed of sound and step to show the results for.
  • Coupling by Frequency: This option shows a plot of the coupling values by frequency of simulation. The step, speed of sound and source-receiver pair are set by the user.
  • Coupling by Step: This option shows a plot of the coupling values by parametric step. The frequency, speed of sound and source-receiver pair are set by the user.
  • Coupling by Speed: This option shows a plot of the coupling values by speed of sound. The frequency, step and source-receiver pair are set by the user.
  • Coupling Text Files: This option allows the visualization of the coupling values for a given step and speed of sound in text format.

 

11.5.1. Coupling Values

This option allows to visualize the coupling values for each source-receiver pair at each frequency, for a user-specified parametric step and speed of sound. The contents of the table will automatically reflect the changes in any of these parameters.

11.5.2. Coupling Charts

The options "Coupling by Frequency", "Coupling by Step" and "Coupling by Speed" under the Results -> Coupling menu allow the user to analyze the dependency the coupling values have with the frequency, the geometry and the speed of sound, respectively, while keeping the other parameters constant. When selecting one of these options, a panel like the following will be shown:

In the left panel, the user can select the independent parameters (those other than the one the coupling values are plotted against -- in the previous figure, that would be the frequency). This allows the user to configure the series they want to plot.

The selected series can be added to the plot by pressing the Add Series button. It is also possible to modify the look of a series previously added to the chart. You can change the color of a particular series by selecting it in the list and pressing the Change Colors

Series can be imported and exported. To save a series click on the Export series button. It is possible to load previously exported series by pressing the Import Series button and locating the file where the results were saved in.

 

11.5.3. Coupling Text Files

This option shows the coupling results as a text file. First, a panel will appear after selecting this option. In this panel, the user needs to select the parameteric step and the speed of sound they want to show the results for. A table will be presented with the coupling values. To save the results click on the Save as... button below the text file.
