Feko is a comprehensive electromagnetic solver with multiple solution methods that is used for electromagnetic field analyses
involving 3D objects of arbitrary shapes.
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.
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.
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.
OPTFEKO is the component that controls the optimisation process. The optimisation parameters are usually associated with
geometric dimensions, material properties, excitations and loadings. For example, the gain of a horn antenna is
maximised by varying the size of the horn aperture.
ADAPTFEKO is the adaptive frequency utility used to automatically select smaller frequency steps near narrow resonances and
larger steps where the results are relatively smooth.
The initfeko.bat (batch file on Windows) and initfeko (bash shell script on Unix / Linux) scripts are executed from a terminal to configure the Feko environment. From this environment, the Feko applications can be launched without using their full path.
The Launcher utility is a single application that allows you quick access to the shortcuts for the Feko components, WinProp components, newFASANT, documentation, Altair license utility and updating parallel credentials. Pin the application to the taskbar for quick launching.
The feko_update_gui utility and the feko_update utility allows you the flexibility to install an update containing features, minor software enhancements and bug fixes
on top of an existing base installation for Altair Feko(which includes Feko, newFASANT and WinProp).
Each major release, upgrade or update is assigned a version number. A version number contains a unique set of numbers assigned
to a specific software release for identification purposes. You can determine from the version number if its an initial
release, update or upgrade.
Updating and upgrading refers to the process of installing a new version containing features, minor software enhancements
and bug fixes on top of an existing base installation.
The feko_update_gui utility and feko_update utility (GUI and command line) use the system proxy by default, although it may be changed or the use of a proxy
suppressed.
Create a local Feko update repository to allow users to update without internet access or to limit the list of update versions that users
can use. Local update repositories can also be used to reduce the amount of data being downloaded by downloading
a repository once and making it available to many local machines or compute clusters.
QUEUEFEKO is a graphical user interface (GUI) application that can create a package which you can transport to a remote queuing system. Created packages can be
extracted once the simulation on the queuing system has been completed.
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.
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.

Update (or upgrade) from a local repository using the graphical user
interface.
Open the Updater using the Launcher utility.
On the Altair Feko update dialog, click the
Settings tab.
Under Update from, click Local
repository to update from a local repository.
Under Local repository, select one of the
following:
If the local repository contains extracted archives or multiple zipped
archives, select Folder (with extracted or zipped
archives) and specify the folder.
The path for the local
Feko update repository must be an
absolute file path which can point to an unmapped network share
(Windows), mapped (mounted) network share or a directory on a local
drive.
Warning: Point the local repository path to the
root folder of the updates.
Example: The Feko updates for the Windows and Linux
platforms were extracted and merged to
C:\Updates. The path to the
local repository points to
C:\Updates.
If the local repository contains a single zipped archive, select
File (zipped archive) and specify the zip
file.
Click Save to save the local repository settings.
Update or upgrade to a new version.
Trouble:Error 16700: Unable to find the file 'XX/YY/manifest.xml.gz'
in the local repository.
Error 16700 indicates that
the path to the local repository is incorrect. The path must point to the root
folder of the local update repository and the folders should not be
modified.
