Feko is a comprehensive electromagnetic solver with multiple solution methods that is used for electromagnetic field analyses
involving 3D objects of arbitrary shapes.
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.
Add up to four legends to a predefined location on the 3D view. Bind the legend to a specific entity (for example, far field data or mesh display), based on the results
displayed in the 3D view.
Store a local copy of the underlying data that is represented by the 3D simulation result. By storing a local copy,
you can modify the existing model and compare the old results to new results.
Show or hide the display of symmetry, the finite difference time domain (FDTD) boundary, the periodic boundary condition (PBC) boundary and the array base element for finite arrays.
A number of mesh display settings are available to give you full control of the mesh rendering in the 3D view. These settings are useful if you want to verify the model (simulation mesh).
View the visibility settings for segments, triangles, apertures, windscreens, tetrahedra, voxels, cuboids and uniform theory of diffraction (UTD) polygons and cylinders.
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 allow 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.
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.
A number of mesh display settings are available to give you full control of the mesh rendering in the 3D view. These settings are useful if you want to verify the model (simulation mesh).
Viewing the Coordinate System for Anisotropic (3D) Media
Validate your model that contains anisotropic (3D) media, by viewing the principal
direction for each medium.
On the 3D View
contextual tabs set, on the Mesh tab, in the
Rendering group, click the Orientation icon. From the drop-down list select the Media (3D) icon.
Each region that has an anisotropic (3D) medium applied to is listed on the
Anisotropic media (3D) settings dialog.
Note: An anisotropic
(3D) medium is applied to a label.
For each region, you can select the Show coordinate
system check box to show the coordinate system in the 3D view.
