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.
Creating Geometry in EDITFEKO
Create geometry in EDITFEKO according to the guidelines to ensure that different mesh parts are electrically connected. Meshes can also be imported to create a model.
Discontinuous Mesh and Geometry Parts
Use domain connectivity (discontinuous Galerkin domain decomposition method) to connect a static mesh to a dynamic parameterised geometry without requiring node connectivity. The parts may be separated by a small gap.
Workflow for Connecting Discontinuous Mesh and Geometry Parts
View the workflow for domain connectivity (discontinuous Galerkin domain decomposition method) to connect discontinuous mesh and geometry parts using CADFEKO to set up the model and EDITFEKO to define the domain connectivity.

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.
- Introduction to EDITFEKO
  EDITFEKO is a scripting interface for advanced users to construct models using a high-level scripting language, which includes FOR loops and conditional IF-ELSE statements.
- Quick Tour of the EDITFEKO Interface
  View the main elements and terminology in the EDITFEKO graphical user interface (GUI).
- PREFEKO Language Concepts
  The language used to create and modify models in EDITFEKO is the PREFEKO language.
- Creating Geometry in EDITFEKO
  Create geometry in EDITFEKO according to the guidelines to ensure that different mesh parts are electrically connected. Meshes can also be imported to create a model.
  - Importing Meshes
    Include a CADFEKO mesh or any other external mesh in the .pre file using the IN card.
  - Guidelines for Mesh Connectivity
    Meshing guidelines are given to ensure electrical connectivity in the mesh.
  - Discontinuous Mesh and Geometry Parts
    Use domain connectivity (discontinuous Galerkin domain decomposition method) to connect a static mesh to a dynamic parameterised geometry without requiring node connectivity. The parts may be separated by a small gap.
    - Workflow for Connecting Discontinuous Mesh and Geometry Parts
      View the workflow for domain connectivity (discontinuous Galerkin domain decomposition method) to connect discontinuous mesh and geometry parts using CADFEKO to set up the model and EDITFEKO to define the domain connectivity.
  - Reducing Mesh Sizes
    Mesh subdivision is a method to reduce the number of mesh elements created / rendered, while still solving the correctly intended mesh.
- Preferences
  EDITFEKO has various default settings that you can configure to customise it to your preference.
- Files Generated by EDITFEKO
  View the files associated and generated by EDITFEKO.
- Shortcut Keys
  View the shortcut keys available for EDITFEKO for faster and easier operation of EDITFEKO.
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.

Workflow for Connecting Discontinuous Mesh and Geometry Parts

View the workflow for domain connectivity (discontinuous Galerkin domain decomposition method) to connect discontinuous mesh and geometry parts using CADFEKO to set up the model and EDITFEKO to define the domain connectivity.

Note: Use this workflow when setting up domain connectivity in EDITFEKO.

Domain connectivity can also be defined in CADFEKO.

Connect discontinuous mesh and geometry parts using the following workflow:

Assemble the model in CADFEKO and define all settings and requests.
Save the model. CADFEKO creates the .pre file.
Open the .pre file in EDITFEKO.
Define the domain connectivity using the DC card.
- Specify the number of connections.
- Define for each connection the labels of the corresponding faces.
  Tip: To view the label names for the relevant faces, view the model in POSTFEKO and colour the mesh by label¹. Add a legend to view the labels per colour².
- Define for each connection a tolerance distance, in order to distinguish between regions, where a gap in the model is desired (or not desired).
Run PREFEKO to create the .fek file for the simulation.
Run the Solver to simulate the model.
