A lot of effort went into the 2019 release of the solvers Altair Feko™ and Altair WinProp™. For both products several performance updates have been achieved and the overall robustness of the produced has been improved. Interfacing with other products has been enhanced, such as a user profile of HyperMesh to Feko and the ability to send simplified Radar Cross Section models (RCS) from Feko to WinProp.

Feko 2019

Diffraction Effects in RL-GO Solver

Diffraction effects for edges and wedges of perfect electric conductors (PEC) have been added to Feko’s RL-GO solver improving its accuracy.

Performance Improvements

The efficiency of power calculations for models using equivalent near field sources has been significantly improved. The example in the below image of a radar antenna placement in a car bumper showed a speed up factor between Feko 2018.1 and 2019 of ~ 90 (time reduction from 175 minutes to 2 minutes on 4 CPUs at 10 cores each) of the power calculation phase.

The GPU support for RL-GO has been extended to include computations with dielectric materials, including dielectric sheets and coatings, resulting in significant performance improvements.

A command line option is now available which can give a good prediction of the necessary solver memory needed to finish an analysis. This option currently supports the following solvers: MLFMM, MoM, PO and FEM.

SPICE circuit and 1-port Touchstone (.s1p) files can now be used to terminate loads.

Solver Interfacing with other Products

Altair HyperWorks 2019™ now provides a dedicated user profile for Feko model files. Users can take advantage of the powerful meshing capabilities in HyperMesh. Material and property assignments are possible, and files can be exported in the Feko native format. The file format is compatible with HyperMesh, CADFEKO and the new HyperWorks 2019 X.

The Feko input deck can be exchanged between CADFEKO and HyperMesh. A dedicated user profile is available in HyperMesh.

WinProp 2019

Object geometry can now be replaced by its Radar Cross Section (RCS) representation. This ensures major savings in simulation time over the full model. The RCS calculation is performed with Feko and imported into WinProp via an ASCII file (.ffe).

Feko calculated RCS information can be included in a WinProp simulation through .ffe file import.

The Signal Level Plan feature in WinProp is a schematic interface that includes the signal generator, cables, signal splitters, and antennas. This schematic now has a more complete and user-friendly display of component information and power levels. Furthermore, it can be exported.

The Monte-Carlo capability in WinProp enables a series of Network Planning simulations with mobile stations distributed randomly, upon which statistical information is extracted, such as what percentage of mobile-phone users can be served. This capability, which was available only in the GUI, has now also been implemented in the WinProp API. Furthermore, several small bugs in the GUI for this capability have been fixed.

The online documentation is now available under the HyperWorks framework. Aside from the move, lots of updates have been done to the documentation and deeper explanations are given in the example’s manual. The launcher allows for direct access to the documentation in either HTML or PDF form.

Online help is now available under the HyperWorks Framework in HTML and PDF file format.
