Feko is a comprehensive electromagnetic solver with multiple solution methods that is used for electromagnetic field analyses
involving 3D objects of arbitrary shapes.
Load a .fek file (single file or multiple files) or load a single POSTFEKO session file that contains the settings, views and references to result files that were present at the time of
save.
When a model containing more than 500 000 elements is opened, it may become difficult to work with the 3D model due to memory
requirements for the 3D rendering and visualisation.
The terms, dataset, slice, trace and 3D result, are used extensively in the documentation. Review the definitions
to get a better concept of these definitions.
Display result data on a graph to allow visual interpretation of the data in a human-readable format, as well as to
communicate the results in reports and presentations.
View the simulation data in a 3D view to allow visual interpretation of the data in a human-readable format, as well as to communicate the results
in reports and presentations. The 3D view can also be used to verify that the CADFEKO or EDITFEKO model is correct.
The Solver contains a number of frequency domain solution methods, as well as a time domain solution method. By default, all
simulation results are obtained in the frequency domain, unless explicitly using the time analysis tool in
POSTFEKO to convert the results to the time domain.
With the time analysis tool in POSTFEKO, electromagnetic scattering problems can be analysed in the time domain. The time domain results are obtained
by applying an inverse fast Fourier transformation (IFFT) on the frequency domain simulation results.
POSTFEKO is a useful tool to help analyse and present data in a useful format. It is often required to use the processed results
in a report or presentation. To help make it easier to generate these reports, several tools are available
in POSTFEKO.
POSTFEKO has a collection of tools that allows you to quickly validate the model, for example, measure distances, measure
angles and finding specific mesh elements.
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.
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.
You can add a model, open an existing project and save the project.
Adding a Model or Project
Load a .fek file (single file or multiple files) or load a single POSTFEKO session file that contains the settings, views and references to result files that were present at the time of save.
Saving a Project
Store the view settings, views and references to result files to a .pfs file to reopen later.
Large Models
When a model containing more than 500 000 elements is opened, it may become difficult to work with the 3D model due to memory requirements for the 3D rendering and visualisation.
