Application Programming Interface (API)
CADFEKO and POSTFEKO have a powerful, fast, lightweight scripting language integrated into the application that allows you to create models, get hold of simulation results and model configuration information and much more.
POSTFEKO API
The POSTFEKO application programming interface provides details regarding the hierarchy of the object as well as the methods, functions and properties available for each object.
Namespaces and Static Functions
Many objects have static functions, but only a limited number of functions are available directly in the application namespace (pf) or sub-namespace.

Release Notes
See what's new in the latest release.
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.

- Meshing
  When meshing a model, you can either use the automatic meshing algorithm to calculate the appropriate mesh settings or you can specify the mesh sizes. When you specify the mesh sizes, the mesh sizes should adhere to certain guidelines.
- SAR Standards
  Feko makes use of a local peak SAR algorithm.

  Control the execution of Feko by specifying the memory management and environment variables.
- Read MAT, LUD, RHS and STR Files
  The .mat file, .lud file and .rhs file are not generated by default, but can be read externally.

  Use the correct structure, convention and syntax for a SPICE circuit definition in Feko.
- List of Acronyms and Abbreviations
  View the list of commonly used acronyms in Feko.
- 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
  A Feko Errors, Warnings and Notes Reference Guide is available as a reference for messages that may be encountered in Feko.

Example

app = pf.GetApplication()
app:NewProject()
app:OpenFile(FEKO_HOME..[[/shared/Resources/Automation/startup.fek]])

    -- Retrieve the far field data set

local farFieldDataSet = pf.FarField.GetDataSet("startup.StandardConfiguration1.FarFields")

    -- Export the data set to a new DRE file

local fileName = [[temp_startup.dre]]
pf.DRE.ExportDataSet(farFieldDataSet, fileName, "/")

    -- Inspect the DRE file hierarchy to determine the location of the data to import
    
local dreFileHierarchy = pf.DRE.DiscoverHierarchy(fileName)
local drePath = "/"..dreFileHierarchy["Groups"][1].Name

    -- Modify scale values used during DRE import

local dbFactor = 10.0
local dbScale = 2.0
local settings = pf.DRE.ImportSettings.Get()
for ii=1,#settings.dBScales do
   if (settings.dBScales[ii].Name == "dBRef") then
      settings.dBScales[ii].dBScale = tostring(dbScale)
   end
end

    -- Import data set from DRE file
    -- Note: The modified scales will not have an effect in this example
    -- (dBRef is not used in the DRE file)

local importedFarFieldDataSet = pf.DRE.ImportDataSet(fileName, drePath, settings)
importedFarFieldDataSet:StoreData(pf.Enums.StoredDataTypeEnum.FarField)
