- 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.
  - Introduction to POSTFEKO
    Use to validate meshed geometry and analyse and post-process results.
    - Reviewing POSTFEKO and Launching OPTFEKO
      Open POSTFEKO from within CADFEKO.
    - User Interface Layout
      View the main elements and terminology in the POSTFEKO graphical user interface (GUI).
    - Validating the Model in POSTFEKO
      View the model using visualisation tools in POSTFEKO to confirm the model was created as intended.
    - Viewing the Near Field Results (3D)
      View the near field results in the 3D view and add a legend and contours.
    - Viewing the Near Field Results (2D)
      Create a new Cartesian graph. Create two near field traces and compare the E_y and E_x components of the near field along the X direction.
    - Viewing the Far Field Results (3D)
      View the far field results in the 3D view.
    - Viewing the Far Field Results (2D)
      View the far field results on a polar graph.
- 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.

User Interface Layout

View the main elements and terminology in the POSTFEKO graphical user interface (GUI).

Quick access toolbar

The quick access toolbar is a small toolbar that gives quick access to actions that are performed often. The actions available on the quick access toolbar are also available via the ribbon. The quick access toolbar includes: New project, Open project, Save project, Undo and Redo.
Ribbon

The ribbon is a command bar that groups similar actions in a series of tabs. The ribbon consists of the application menu, core tabs and contextual tab sets.
Project browser

The project browser is a panel that lists the models loaded in the current project, imported data, stored data and scripted data.
Tip: Collapse the project browser to expand the 3D view.
On the View tab, in the Show group, click the Project icon.
Model browser

The model browser is a panel that organises the model information of the selected model in the project browser (3), into two separate tabs.

Model tab

The Model tab lists the model information and results for the selected model.

Results tab

The Results tab lists the results and solution information.
Details browser
The details browser is a panel that shows in-depth detail for the selected item in the model browser (4).
Tip: View the solution information for the selected model.
On the model browser (Results tab), click Solution information to view:

start and end time

memory per process

total CPU-time
Status bar

The status bar is a small toolbar that gives quick access to general display settings, tools, and graph cursor settings.
3D view/2D graphs

3D view

The 3D view displays the geometry, mesh, solution settings as well as 3D results.

2D graphs

The 2D graphs display the 2D results on either a Cartesian graph, polar graph, Smith chart or Cartesian surface graph.
Tip:
- Re-order the window tabs by simply dragging the tab to the desired location.
- Rename the window tab by using the right-click context menu and selecting Rename.
Result palette

The result palette is a panel that gives access to options that control the data in the 3D view or 2D graph for the relevant result type. For example, 3D far field data allows the phi cut plot type and gain in dB to be specified.
Help

The Help icon gives quick access to the Feko manuals.
Tip: Press F1 to access context-sensitive help.
Search bar

The search bar is a single-line textbox that allows you to enter a keyword and search for relevant information in the GUI. Entering a keyword in the search bar will populate a drop-down list of actions as well as the location of the particular action on the ribbon or context menu. Clicking on an item in the list will execute the action.
Application launcher

The application launcher toolbar is a small toolbar that gives quick access to other Feko components.
