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, WRAP components, 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).
You have the option to send the crash report to the Altair Feko development team with a description of the steps leading up to the crash. Crash reports can help the development
team locate and correct problems faster.
A crash report can be exported to a .zip file and emailed to Altair Technical Support. Use this workflow when the machine where the crash occurred is not connected to the internet.
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.
A crash report can be exported to a .zip file and emailed to Altair Technical Support. Use this workflow when the machine where the crash occurred is not connected to the internet.
Exporting a Crash Report When Not Connected to the Internet
A crash report can be exported to a .zip file and emailed to Altair Technical Support.
Use this workflow when the machine where the crash occurred is not connected to the
internet.
In the event of a crash occurring in CADFEKO, POSTFEKO or EDITFEKO, the crash report utility generates a crash
report.
Select one of the following options:
To attach the model files and any related files
to the crash report, click Attach model files before
sending.
If you are working on a confidential model and
do not want to send the model files, click Send report without
model.
The POSTFEKO has stopped
working dialog is displayed while the details regarding the
location where the crash occurred are collected.
When the crash report is generated, the Error
Report dialog is displayed.
Note: The file size of the report is indicated at the top of the
dialog.
On the Error Report dialog, click What does
this report contain to view the files contained in the crash
report.
The Error Report Details dialog is displayed.
On the Error report details dialog, view the list of files
and export to a .zip
file.
To view the data contained in a file, delete a file or add more files,
click the file and from the right-click context menu, select the
relevant option.
Click Export to export the files listed on the
Error Report Details dialog to a
.zip file.
Browse to the desired file location and specify a file name.
Click Close to close the Error Report
Details dialog.
On the Error Report dialog, click Other actions > Close the program.
Copy the exported .zip file to
a machine that is connected to the internet and email the file to Altair Technical Support.
Note: Refer to the Privacy policy1 for more information regarding how we use the information obtained from
the crash report.
