- Creating a Rectangular Horn
  The example is intended for users with no or little experience with CADFEKO. It makes use of a completed rectangular horn model to familiarise yourself with model creation in CADFEKO and viewing the simulated results in POSTFEKO.
  - Example Overview
    This example shows a completed rectangular horn model to familiarise yourself with the Feko components and workflow. The main elements and terminology in the CADFEKO and POSTFEKO graphical user interface are discussed.
  - Topics Discussed in this Example
    Before starting this example, check if the topics discussed in this example are relevant to the intended application and experience level.
  - Example Prerequisites
    Before starting this example, ensure that the system satisfies the minimum requirements.
  - Feko Components and Workflow
    View the typical workflow when working with the Feko components.
  - Introduction to CADFEKO
    Use to configure a solver-ready input file for simulations.
    - Launching CADFEKO (Windows)
      There are several options available to launch CADFEKO in Microsoft Windows.
    - Launching CADFEKO (Linux)
      There are several options available to launch CADFEKO in Linux.
    - Start Page
      The Feko start page is displayed when starting a new instance (no models are loaded) of CADFEKO, EDITFEKO or POSTFEKO.
    - User Interface Layout
      View the main elements and terminology in the CADFEKO graphical user interface (GUI).
    - Ribbon
      The ribbon is a command bar that groups similar actions in a series of tabs.
    - Construction Tab
      The Construction tab contains the geometry and mesh representation of the current model in a tree structure. It also lists ports and the optimisation configuration.
    - Configuration Tab
      The Configuration tab contains the global and configuration-specific model settings and requests of the current model in tree form.
    - Notification Centre
      The Notification centre performs computational electromagnetic model (CEM) validation and shows the status of the model and notifications.
    - Dialog Error Feedback
      CADFEKO provides error feedback for dialogs by showing a soft message bubble when validation fails on a dialog.
    - Custom Keyboard Shortcut Settings
      CADFEKO provides default keyboard shortcuts. To better fit your workflow and work style, you can reassign keyboard shortcuts to different commands.
    - Custom Mouse Bindings
      CADFEKO provides default commands for all the mouse buttons. To better fit your workflow and work style, you can reassign mouse buttons to different commands.
  - Introduction to POSTFEKO
    Use to validate meshed geometry and analyse and post-process results.
- Creating CADFEKO Models
  The example is intended for users with no or little experience with CADFEKO. This example is not an example intended for simulation, but rather to familiarise yourself with model creation in CADFEKO.
- GPS Patch Antenna
  The example considers a left-handed circular polarised GPS patch antenna on a finite substrate.
- GPS Patch on Quadcopter
  The example considers the antenna placement of a GPS patch antenna on a quadcopter.
- EMC Coupling
  The example considers the coupling between a typical monopole antenna and a loaded transmission line above a ground plane.
- Waveguide Power Divider
  The example considers the transmission and reflection coefficients of a waveguide power divider.
- Optimisation of Bent Dipole and Plate
  The example considers the optimisation of the gain of a bent dipole in front of a plate.
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.
Appendix
Reference information is provided in the appendix.

Dialog Error Feedback

CADFEKO provides error feedback for dialogs by showing a soft message bubble when validation fails on a dialog.

Click the

icon to show or hide the message bubble or click elsewhere in CADFEKO to hide the message bubble. The error feedback is also shown per tab when the validation fails on a multi-tab dialog.
