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.

- Summary of Files
  Feko creates and uses many different file types. It is useful to know what is stored in the various files and weather they were created by Feko and if it is safe to delete them. The files are grouped as either native files that have been created by Feko or non-native files that are supported by Feko. Non-native files are often exported by Feko even if the formats are not under the control of the Feko development team.
- Common Errors and Warnings

`FrequencyExportSettings`

Properties that control how continuous frequency is sampled for exporting. These properties are only valid when Frequency Type is Continuous.

Example

application = cf.Application.GetInstance()
project = application:NewProject()

    -- Initialise the frequency to a continuous band

frequency = project.Contents.SolutionConfigurations.GlobalFrequency
properties = frequency:GetProperties()
properties.Start = 100e6
properties.End = 200e6
properties.RangeType = cf.Enums.FrequencyRangeTypeEnum.Continuous
frequency:SetProperties(properties)

    -- Set the number of samples for export
    -- As the properties need to be modified in one step,
    -- a properties table is used

properties = frequency:GetProperties()
properties.Export.NumberOfSamplesEnabled = true
properties.Export.NumberOfSamples = 10
frequency:SetProperties(properties)
