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.
- 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.
- CADFEKO Application Macros
  A collection of Lua application macros are available to automate repetitive tasks in CADFEKO.
- POSTFEKO Application Macros
  A collection of Lua application macros are available to automate repetitive tasks in POSTFEKO.
  - Characteristic Mode Plotter
    This POSTFEKO application macro can be used to plot all the standard parameters that are available after a characteristic mode analysis simulation was performed.
  - MIMO Performance Evaluation
    This application macro is used for calculating mean effective gain (MEG) and envelope correlation coefficient (ECC) for a MIMO antenna configuration. The MEG ratio can also be plotted.
  - Multiport Post-Processing
    The Multiport post-processing application macro allows you to calculate results for changes in the port loading without rerunning the Solver. Results that are supported are far fields, near fields, currents and specific port parameters, for example, the voltage, current and S-parameters of each port.
  - Plot Multiple S-Parameter Traces Macro
    Plot multiport S-parameter results.
  - Tile Windows
    An application macro to tile any POSTFEKO views side-by-side.
  - Plot Interference Matrix
    This application macro uses the S-parameter data from a Feko simulation to display a coupling matrix for a multi-port scenario.
  - Characteristic Mode Synthesis and Design
    The characteristic mode synthesis and design application macro is a post-processing application macro that can be used to calculate a weighted sum for the currents, near fields, and far fields requests for specific characteristic modes of interest. The application macro uses a modified version of the modal weighting coefficient (MWC) to use the radiating phase when synthesising the results with the macro.
  - Other POSTFEKO Application Macros
    A collection of smaller POSTFEKO application macro are available, but these macros do not include step-by-step instructions.
- Shared Application Macros
  A collection of Lua macros are available to automate repetitive tasks where the workflow span both 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.
Appendix
Reference information is provided in the appendix.
