CADFEKO
Features
- Added a PCB equivalent source that uses printed circuit board current data imported from Altair PollEx.
- Extended the Solver settings dialog with an option to export files for thermal analysis when running the Feko solver.
- Extended CEM validate to issue a warning if the wideband circuit crosstalk method could be utilised for cable harnesses, but there are requests in the model that will trigger a full-wave solution.
EDITFEKO
Features
- Added the AJ card for importing printed circuit board (PCB) current data from PollEx. An equivalent source is defined that uses the current data as impressed line currents.
- Extended the DA card (settings for writing additional data files) with the option to export files for thermal analysis.
POSTFEKO
Features
- Increased the .fek file version to 172 to accommodate new features.
- Added support for the new PCB equivalent source that uses PollEx current data.
- Upgraded the library that is used to export animations. The file size of exported animations in .gif format is greatly reduced. The file size of example exports were up to 50 times smaller compared to the previous version using the same export settings. There is also more variation between the different export quality setting for animations in .mov format than before, providing better control over the resulting export by using different combinations of the export size and export quality settings.
- Added support for .mkv format when exporting animations.
- Improved the implementation of 2D Display OpenGL rendering in POSTFEKO.
Note: Enable OpenGL rendering for 2D graphs to improve performance when interacting with traces that have a large number of points, in particular those that have many overlapping lines.
Solver
Features
- Added support for parallel simulations with the direct ACA solver on machines with distributed memory architecture (parallel support on multiple nodes).
- Substantially improved parallel load balancing for the MLFMM. Models with a combination of fine detail and uniform meshes often resulted in some MLFMM boxes with many more elementscompared to other boxes. The non-uniform distribution of elements between boxes could have resulted in a few boxes dominating the solution time and increasing the number of cores would not result in faster solutions. The matrix fill times now scale linearly with the number of cores used for the parallel simulation.
- Improved transfer function computation for MLFMM. Both the memory footprint and the computation time for transfer functions are decreased.
- Decrease the memory footprint for the MLFMM solution phase by using shared memory for matrix by vector multiplication.
- Added support for a wideband solution for cross-talk calculations of cable circuits. A speed-up of up to two orders of magnitude can be observed for the cross-talk calculation phase when comparing to Feko 2019.3.2 where cross-talk was calculated on a per frequency basis. Additionally, improved the efficiency of the overall circuit cross-talk solution by allowing certain phases of a MoM or FDTD cable solution to be skipped in a configuration where only circuit cross-talk is required to be calculated.
- Added support for curvilinear elements in the 2D FEM solution of per-unit-length elements of cable cross-sections.
- Refined the error checking mechanism for validating circuit connections at cable path endpoints to only issue an error message if explicit direct connections across a shield exist in the circuit.
- Improved the integration routines used for wire segments, resulting in a performance improvement for the matrix fill stage of the solution of models with many wire segments.
- Improved the time efficiency of FEM matrix elements computation.
- Power loss in lossy segments, triangles, FEM and VEP tetrahedra, as well as metallic triangles on or in a FEM region are now exported to a .epl file, along with the Cartesian coordinates of the centre of each element, its size and label.
- Added support for using PCB current data calculated in PollEx as an impressed current source.
- NGSPICE is no longer included in the Feko installation. It can still be used as the SPICE solver in Feko if it is available.
- Continuation lines, represented by the "+" character, can now be used in SPICE netlist definitions.
Resolved Issue
- Fixed a bug that resulted in inaccurate results for an MLFMM solution of models with dielectric faces touching an infinite PEC ground plane.
Shared Interface Changes
Features
- Updated the applications and documentation with the latest Altair branding.
- Introduced new application icons to provide a more uniform appearance across HyperWorks applications.
Support Components
Features
- Upgraded licensing to use the latest Altair License Management System 14.5.1. Components using ALM 14.5.1 require servers running Altair License Server 14.5.1.
- Extended the installer with the End User License Agreement (EULA) shown on the first panel. This requires an update to the response file when running the installer in silent mode.
- Upgraded the version of Java used by the installer to Java ™ Runtime Environment, Update 202 (JRE 8u202).
- Extended PREFEKO to read PCB current data from a PollEx .rei file.
Resolved Issues
- Added a check to the installers to prevent overwriting existing installations when installing using console mode on Linux.
- Resolved an issue with the keytips of the Feko Launcher that prevented some actions being performed using keyboard navigation.
The most notable extensions and improvements to WinProp are listed by component.
General
Features

- An updated and unified WinProp Example Guide is now available in PDF and as part of the HTML documentation. It can be accessed from the Launcher utility.
- Updated the location of the WinProp examples. The models are moved to the ExampleGuide_models folder inside the examples folder. The new default location of the models is: C:\Program Files\Altair\2020\help\winprop\examples\ExampleGui de_models.
ProMan
Features
- Simplified the workflow for simulation of co-existence of different wireless systems. Results for one wireless system can easily be included in a simulation of another wireless system (and vice versa).
- Simplified the workflow for inclusion of external interference. External interference can be based on the imported propagation result of another project or be defined as a general background noise. The suppression of interference by filters can be specified when applicable, or omitted if the interfering signal is exactly at a carrier frequency of interest.
- Simplified the definition of antenna sites for MIMO. Specifying similar parameters for multiple antennas used to involve repetitive work. The new (optional) MIMO site saves the user setup time and reduces the chance of making occasional mistakes.
- Added the capability to create copies of an antenna from the Site dialog in ProMan.
- Some network planning results are now selected by default when a new project is created.
- Added support for moving prediction points in a time-variant database simulated with the IRT model.
- Added support for breakpoint distance and propagation exponent definitions in the SRT model.
- LOS and NLOS exponents are now considered during calibration of the SRT propagation model.
- The minimum power that can be set at the transmitter is now -79 dBm.
- Added support for exporting animations in .avi and .mov formats, using H.264 and msmpeg4v2 codecs, with the possibility to export animations in different qualities (high, normal and low).
Resolved Issues
- The breakpoint distance of transmitters located directly above buildings is now correctly considered in simulations with the DPM model.
- Fixed a bug when computing the breakpoint distance solving indoor projects that include topography with the dominant path prediction model.
- Fixed a bug in the computation of the breakpoint distance during predictions with the rural dominant path model for projects where either the transmitter or prediction height is chosen to be at an absolute height above sea level.
- Additional gains due to beam-forming are now fully considered in 5G network planning projects.
- Fixed a bug that resulted in a crash during network planning when a project is simulated in trajectory mode and the option to provide additional output for visualisation of data streams is activated.
- Resolution and height of prediction points can now be modified in ProMan for IRT projects with databases preprocessed in point mode.
- Improved the performance of parallel urban IRT predictions by a factor of up to 1.5x. Additionally, resolved issues due to uninitialised variables.
- Fixed a bug which causes propagation paths to be slightly shifted from the pixel centers for urban scenarios solved with DPM.
WallMan
Resolved Issues
- Resolution and height of prediction points can now be modified in ProMan for IRT projects with databases preprocessed in point mode.
- Fixed a bug that resulted in a separate material layer being created for each building when converting a file in the .shp format to the WinProp .odb format, despite all buildings having the same material properties. This fix improves the time and memory efficiency of database conversion resulting in smaller converted .odb databases being generated in a much shorter time than with previous versions.
AMan
Feature
- Improved the functionality to easily generate beams and envelope patterns to include polarization information.
Application Programming Interface
Features
- ProMan simulations can now be run in batch mode, from the command line, using the WinPropCLI executable on Windows or Linux. The WinProp command line interface can be used within queuing systems such as Altair PBS, Torque, LSF and GridEngine.

- Added API functions to directly export the clutter maps (.asc) as well as clutter properties (.mct) in ASCII format. The exported clutter maps can readily be converted to the WinProp binary format in WallMan.
- Path loss exponents and breakpoint distance parameters of the SRT model are now accessible via the API.
- Scattering properties of materials are now also considered in the API.
- IRT preprocessing in the API is no longer limited to 9 threads.
