Example 4: Command-Line Interface

The multiport application macro supports calculation from the command-line by calling the application macro via POSTFEKO.

The first example shows how to use a Feko model with the interface. The second example uses a Touchstone file as input.

A pre-configured Lua settings file is used from Example 1: Feko Model as Input. The settings file contains a processingOptions table which is used to set up the settings required for a multiport run from the command-line. Both examples use the same Lua settings file. The Lua settings file is configured to export the scaling coefficients to file which can be used in other post-processing applications.

Note: The settings file can be automatically generated by using the Save settings to file (*.lua) check box on the Processing options dialog from the GUI.
