Scripts and Application Programming Interface (API)
CADFEKO and POSTFEKO have a powerful, fast, lightweight scripting language integrated into the application allowing you to create models, get hold of simulation results and model configuration information as well as manipulation of data and automate repetitive tasks.
Command Line Arguments for Launching Script
A script can be run via the command line.

Get Started
The Feko Getting Started Guide contains step-by-step instructions on how to get started with Feko.
Examples
The Feko Example Guide contains a collection of examples that teaches you Feko concepts and essentials.
Introduction to Feko
Feko is a comprehensive electromagnetic solver with multiple solution methods that is used for electromagnetic field analyses involving 3D objects of arbitrary shapes.
CADFEKO
CADFEKO is used to create and mesh the geometry or model mesh, specify the solution settings and calculation requests in a graphical environment.
POSTFEKO
POSTFEKO, the Feko post processor, is used to display the model (configuration and mesh), results on graphs and 3D views.
EDITFEKO
EDITFEKO is used to construct advanced models (both the geometry and solution requirements) using a high-level scripting language which includes loops and conditional statements.
Feko Solution Methods
One of the key features in Feko is that it includes a broad set of unique and hybridised solution methods. Effective use of Feko features requires an understanding of the available methods.
Optimisation in Feko
Feko offers state-of-the-art optimisation engines based on generic algorithm (GA) and other methods, which can be used to automatically optimise the design and determine the optimum solution.
Feko Utilities
The Feko utilities consist of PREFEKO, OPTFEKO, ADAPTFEKO, the Launcher utility, Updater and the crash reporter.
Description of the Output File of Feko
Feko writes all the results to an ASCII output file .out as well as a binary output file .bof for usage by POSTFEKO. Use the .out file to obtain additional information about the solution.
Feko Application Macros
A large collection of application macros are available for CADFEKO and POSTFEKO.
Scripts and Application Programming Interface (API)
CADFEKO and POSTFEKO have a powerful, fast, lightweight scripting language integrated into the application allowing you to create models, get hold of simulation results and model configuration information as well as manipulation of data and automate repetitive tasks.
- Introduction to Scripting and the API
  The scripting language that has been integrated with CADFEKO and POSTFEKO is called Lua. Lua has a syntax that is similar to Python and Matlab (or Octave) and is easy to learn and use.
- Script Editor
  The script editor allows you to create scripts based on the Lua language to control CADFEKO, POSTFEKO and other applications as well as manipulation of data to be viewed and analysed further in POSTFEKO.
- Macro Recording
  Use macro recording to record actions in a script. Play the script back to automate the process or view the script to learn the Lua-based scripting language by example. Macro recording allows you to perform repetitive actions faster and with less effort.
- Scripting Basics
  The scripting capability is powerful and help your work to be completed faster, but you first need to learn the basics of Lua and scripting in Feko.
- Script Types
  There are two types of scripts that are supported in Feko, API scripts and result scripts. POSTFEKO supports both types of scripts, while CADFEKO only supports API scripts. It is important to use the correct script type in POSTFEKO to ensure that the desired result is achieved.
- Custom Dialogs (Forms)
  During the execution of an automation script, custom dialogs can be used that allows the script to be more interactive. When used in conjunction with the custom command library, it is possible to extend the user interface for a variety of custom workflows.
- Application Macros
  An application macro is a reference to an automation script, an icon file and associated metadata.
- Application Macro Library
  The application macro library allows commonly used application macros to be stored in a repository.
- Command Line Arguments for Launching Script
  A script can be run via the command line.
Appendix
Reference information is provided in the appendix.

Command Line Arguments for Launching Script

A script can be run via the command line.

Command-line options:

cadfeko [FILENAME] [OPTIONS]

postfeko [FILENAME] [OPTIONS]

FILENAME

Name of the .cfx or .lua file to load. If the model does not exist, a new empty model is created with this name.

OPTIONS

-h, --help: Displays the help message.
--version: Print the version information and then exit.
--non-interactive: Special execution mode for running automation scripts without user interaction.
--run-script SCRIPTFILE: Specifies an automation script to load and run.
Note: When running a script, the working directory is set to the script to be run before running the script.
--configure-script CONFIGSTRING: Executes the string CONFIGSTRING before running the script specified in SCRIPTFILE. This option is only used with the non-interactive option.
