Feko 2022.0.1 Release Notes
The most notable extensions and improvements to Feko are listed by component.
CADFEKO
Resolved Issues
- Made improvements to volume meshing performance after changes introduced in Feko 2021.2.2 may have caused volume meshing to be slower.
- Resolved an issue with CEM validate incorrectly reporting an error for models containing SEP regions and finite arrays to be solved with the domain Green's function method (DGFM). This combination is supported.
- Resolved an issue with the visualisation of connector pins in the cable harness schematic view in Feko 2022.
- Resolved an issue that may have prevented reading solutions from an existing .str file for models containing circular waveguide ports. This could have caused unintended re-calculation of solutions rather than using existing solutions. For models that suffered from this behaviour, the .str will need to be created once using this version of Feko. The behaviour in subsequent simulations should be as expected. This change will affect the precision of values used in waveguide port point definitions generally.
- Resolved an issue where the properties of a cable shield could not be set through the API if the cable shield previously referenced a medium that no longer exists in the model.
- Resolved an issue where the outer radius of a cable bundle was required to be much larger than the minimum Total shield radius value displayed on the Advanced tab of the Cable shield dialog of the cable shield applied to the bundle.
- Resolved an issue with the number of frequency points written out by the Parameter Sweep: Create Models application macro. This could have triggered a Number of frequency points mismatch error when using the Parameter Sweep: Combine Results application macro in POSTFEKO.
- Resolved the issue that only complex impedance loads could be added to transmission line ports. All load types, for example series or parallel circuits, can now be applied to transmission line ports.
- Resolved an assertion failing with the message Assertion failed: getLayer() when working with network schematics. After deleting network schematic elements in a certain order, the assertion failure could be encountered in various ways, including further modifications to the model, re-opening the model after saving it, or when importing another .cfx model
POSTFEKO
Resolved Issue
- Resolved an issue with Cartesian graphs where the graph axes were not updated correctly when the axis unit changed due to changes made to the graph. Showing or hiding a trace with a different range from the plotted traces may have seemed to cause traces to disappear from the graph until zooming to extents or re-applying the Axis settings.
Solver
Feature
- Improved the robustness of creeping ray path computations near transition regions of faceted UTD models.
Resolved Issues
- Improved the accuracy of receiver power calculations in coupled MoM/RL-GO or MoM/faceted UTD simulations.
- Improved the efficiency of the Huygens source processing phase of an RL-GO solution, resulting a speed-up of up to 35% for in some cases.
- Corrected an error that may have reaulted in inaccurate calculation of power when using the receiving antennas with faceted UTD solver.
- Resolved an issue that may have resulted in unexpected termination of the solution or inaccurate results when using the ACA solver with plane wave source/s looped over multiple directions.
- Resolved an internal error that occurred during the calculation of interpolation tables of a model with a planar multi-layer substrate and wire ports.
- Resolved an issue where results for angles of incidence in a loop of multiple plane waves that were already completed may not have correctly been loaded and shown in POSTFEKO if the user terminates the simulation.
- Optimize the calculation phase of the spherical mode receive antenna.
- Cable analysis problems solved using the MTL method using will not incorrectly trigger error 55007. This resolves an error introduced in Feko 2022.
- Resolved a regression in Feko 2022 that resulted in longer runtimes than expected when re-using solution coefficients from a .str file with the MLFMM solver.
- Resolved an issue that may have caused rapid non-physical variations in the reflection coefficient phase when solving some periodic structures using periodic boundary conditions.
- Resolved an issue that resulted in multiple .ffe files, each containing a single direction, being written out for monostatic RCS requests in a recent release. A single .ffe file containing results from all directions is now written to disk.
- The test to determine when grating lobes may impact on results for simulations using oblique PBC unit cells has been refined so that a warning about potential inaccuracies is only given when relevant.
- An MPI error that occurred in some combinations of parallel processes stating that message sizes do not match across processes is now avoided.
Shared Interface Changes
Resolved Issue
- Resolved an issue where In-App Licensing was used instead of HPC Licensing when the Solver was started from a Feko Terminal opened from within a Feko graphical user interface (GUI) application. HPC Licensing should apply where a solver is not started from inside a graphical user interface application and a SolverHPC license feature is present. Feko Terminals opened from the Launcher utility was not affected by this issue.
Support Components
Feature
- The automatic mesh refinement script has been extended to cater for simulation models that include referenced files.
Resolved Issues
- Resolved an issue where opening the Feko help from the Launcher utility invoked two instances of the help in the web browser.
- Resolved an issue that may have caused a memory violation when a large number (> 500) samples were required in ADAPTFEKO.
- Added consistency checks and a more verbose error message when importing near field files as equivalent sources or receiving antennas.
- Resolved the issue that the Feko help could not be opened from the Launcher utility in server installations.

Feko is a comprehensive computational electromagnetics (CEM) software product used widely in the telecommunications, automotive, aerospace and defense industries.
The name Feko is an abbreviation derived from the German phrase “FEldberechnung bei Körpern mit beliebiger Oberfläche” (field computations involving bodies of arbitrary shape). As the name suggests, Feko can be used for various types of electromagnetic field analyses involving objects of arbitrary shapes. Feko offers several frequency domain electromagnetic (EM) solution methods as well as a time domain method under a single license. Hybridisation of these methods enables efficient analysis of a broad spectrum of EM problems, including antennas, microstrip circuits, radio frequency (RF) components and biomedical systems, the placement of antennas on electrically large structures, the calculation of scattering (RCS), as well as the investigation of electromagnetic compatibility (EMC).
Feko offers tools that are tailored to solve the more challenging EM interactions, including dedicated solvers for characteristic mode analysis (CMA) and bi-directional cables coupling. Special formulations are included for efficient simulation of integrated windscreen antennas and antenna arrays.
Combined with the multilevel fast multipole method (MLFMM), and true hybridisation of the solvers, Feko is considered the global market leader for antenna placement analysis.
