Altair FEKO 2022.0

Altair FEKO 2022.0

The software developer Altair is pleased to announce the availability of Feko 2022.0.0 is a major release with new features, corrections and improvements.

Highlights of the 2022 Release

The most notable extensions and improvements to Feko, WinProp and newFASANT in the 2022 release.

Salient Features in Feko

– The flexibility of Feko solvers has been extended to support hybrid simulations where faceted UTD is used to solve some parts of the model and other parts are solved with the MoM. Both fully coupled and uncoupled simulations are supported, though dielectrics in the MoM region are not yet supported. Receiving antennas (defined using far field, near field or spherical modes) may also be included in the simulation. Additional optical effects as well as higher-order effects are added to the faceted UTD enabling more accurate simulations for many cases

– Improvements in the application of shared memory and low-level MPI optimisations in the MLFMM solution result in improved parallel efficiency (both runtime and memory) for highly distributed simulations (across multiple nodes).

Salient Features in WinProp

– The calculation of Doppler shift due to movement or rotation of objects around any 3D axis has been added.

– Higher accuracy of solutions using the SBR (Shooting Bouncing Rays) solver is achieved by using a hybrid ray tracing approach which employs path verification from standard ray tracing.

– When viewing radio-coverage results in a 3D view, transmitter antenna patterns can be displayed – allowing for easier visual verification and interpretation of the results.

– The API has been extended to support the generation of 5G beam patterns as well as automation of FM-CW post processing.

Salient Features in newFASANT

– A new workflow has been added to get accurate and fast simulation results for even more complex and realistic multi layer radomes with frequency selective surface (FSS) structures in newFASANT. The radome and FSS is first characterised in terms of reflection/transmission and is then applied as a material to the relevant surface when configuring the full radome analysis.

– The <keyword keyref="method_mom_acronym"/> module now supports the usage of the Characteristic Basis Function Method (CBFM) for non-RCS calculations.

– Near fields calculated using Feko solvers on a Cartesian boundary in *.efe/*.hfe format may now be imported as a simulation source.
