The Feko Getting Started Guide contains step-by-step instructions on how to get started with Feko.
The Feko Example Guide contains a collection of examples that teaches you Feko concepts and essentials.
Feko is a comprehensive electromagnetic solver with multiple solution methods that is used for electromagnetic field analyses involving 3D objects of arbitrary shapes.
CADFEKO is used to create and mesh the geometry or model mesh, specify the solution settings and calculation requests in a graphical environment.
POSTFEKO, the Feko post processor, is used to display the model (configuration and mesh), results on graphs and 3D views.
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.
The Feko utilities consist of PREFEKO, OPTFEKO, ADAPTFEKO, the Launcher utility, Updater and the crash reporter.
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.
A large collection of application macros are available for CADFEKO and POSTFEKO.
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.
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.
Each geometry and calculation request are entered on a separate line in the .pre and are referred to as cards.
A collection of how-tos are included that covers advanced concepts.
Question: How are the per-unit-length parameters, L, C and G calculated for MTL cables (including thick shields)?
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.
Feko makes use of a local peak SAR algorithm.
Control the execution of Feko by specifying the memory management and environment variables.
The .mat file, .lud file and .rhs file are not generated by default, but can be read externally.
Feko integrates with various products within Altair Simulation Products such as HyperStudy. Integration with third-party products is also supported through the powerful scripting and plug-in infrastructure.
Use the correct structure, convention and syntax for a SPICE circuit definition in Feko.

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.
A Feko Errors, Warnings and Notes Reference Guide is available as a reference for messages that may be encountered in Feko.
