Release Notes: Altair Feko 2023
Altair Feko 2023 is available with new features, corrections and improvements. Altair Feko 2023 is a major release. It can be installed alongside other instances of Altair Feko.

The most notable extensions and improvements to Feko, newFASANT, WinProp and WRAP in the 2023
release.
Salient Features in Feko
- A selection of new components was added to the CADFEKO component library. Ten new antenna models (including antennas for EMC testing) and four new platform models were added.


- The Altair Material Data Centre is now populated with media from CADFEKO. Import the media and use in Feko simulations.
- Reduced solution method limitations:
. SEP regions (dielectrics) can be used in the MoM part of the solution for coupled and uncoupled scenarios with RL-GO.
. Lossy dielectrics can be included in characteristic mode analysis calculations.
. Loading restrictions have been relaxed to model direct/strong coupling between the inner and outer regions at the cable terminations in combined MoM/MTL simulations.
- A new tool (AMRFEKO) is now available, which enables automatic adaptive mesh refinement based on error estimates for FEM and MoM/FEM solutions. The fully-automatic tool can be launched from a command prompt or any of the Feko GUIs and can also be used on HPC resources in a similar fashion to RUNFEKO.


- A new domain connectivity approach allows meshes of specific parts to be treated as if "connected" during MoM and MoM/MLFMM solutions in places where the borders of the meshes are close together, even if the mesh vertices on those borders are not coincident. Domain connectivity can now be configured in CADFEKO (new in 2023) or EDITFEKO (since 2022.3) and visualized in POSTFEKO (new in 2023).


- CBFM is a modification of the conventional method of moments (MoM) that reduces the number of unknowns using macro basis functions. This approach could be used with MoM from Feko 2022.3 but is now available for use with MoM/MLFMM - helping achieve a substantial performance improvement over MLFMM in some applications such as monostatic RCS calculations of large objects with similar solution accuracy compared to the default solution.


Salient Features in WinProp
- Modified the beam assignment algorithm to use the rays of the receiving pixel leading to more accurate results.


- Arbitrary prediction planes can now be viewed in the 2D view by selecting the plane from the prediction plane drop-down list. In the past, arbitrary prediction planes could only be viewed in the 3D view. This option is useful when viewing vertical planes of the Parabolic Equation (PE) model.


- The pixel center and pixel grid can be enabled on the Default Settings dialog.


- Added the new wireless standard definition files (.wst[1]) for WiFi 7 (802.11be) and updated WiFi 6 (802.11ax). ProMan was extended to support the new 4096-QAM transmission modes for WiFi 7 (802.11be).
Salient Features in WRAP
- Added a new and improved format for height and landcover maps to WRAP and MapDataManager that have non-integer resolutions and are backwards compatible with the old format. To support coordinates and resolutions with non-integer arc second values, modifications were made to MapData Manager and height/clutter data reader functions. For this new format, WRAP supports horizontal resolution in micrometers, and vertical resolution in mm. This will assist detailed prediction and planning, involving maps with finer vertical and horizontal details of height and clutter (land use) data.
- The ITU-R P. 1409 propagation model was added to WRAP, which provides propagation predictions for radio communication systems or networks using high-altitude platform stations (HAPS) or other elevated stations in the stratosphere. The model is valid from 1 GHz and above.


- Added support to calculate the LTE sub-carrier interference between neighbouring co-channel LTE base stations. The user has the option to select the strongest co-channel interference only, or all interference, in addition to defining the cell load. The option is used when LTE transmitters exist in coverage calculations that make use of interference, for example, RSSI, RSRQ, Data rate, Throughput, SINR.


Altair Simulation-driven design changed product development forever, enabling engineers to reduce design iterations and prototype testing. Increasing scientific computing power expanded the opportunity to apply analysis, making large design studies possible within the timing constraints of a program. Now engineering adoption of AI is transforming product development again. The combination of physics-based simulation-driven design with machine learning, leveraging the latest in high-performance computing, enables teams to explore more and identify high-potential designs - while rejecting low-potential concepts - even earlier in development cycles.
Fekois a powerful and comprehensive 3D simulation package intended for the analysis of a wide range of electromagnetic radiation and scattering problems. Applications include antenna design, antenna placement, microstrip antennas and circuits, dielectric media, scattering analysis, electromagnetic compatibility studies including cable harness modelling and many more.
WinPropis the most complete suite of tools in the domain of wireless propagation and radio network planning. With applications ranging from satellite to terrestrial, from rural via urban to indoor radio links, WinProp's innovative wave propagation models combine accuracy with short computation times.
newFASANTcomplements Altair's high frequency electromagnetic software tool (Altair Feko) for general 3D EM field calculations, including, among others, special design tools tailored for specific applications like complex radomes including FSS, automated design of reflectarrays and ultra-conformed reflector antennas, analysis of Doppler effects, ultrasound systems including automotive or complex RCS, and antenna placement problems. Advanced solver technologies like the MoM combined with the characteristic basis functions (CBFS), PO/GO/PTD, GTD/PO and MLFMM parallelised through MPI/OpenMP, being some of them especially efficient for the analysis of electrically very large problems.
WRAPis a comprehensive tool for electromagnetic propagation, antenna collocation and spectrum management. WRAP combines propagation analysis, often over large areas with many transmitters and receivers, with system analysis to include complex non-linear equipment properties.
