Altair HW FEKO and WinProp 2019.2.0 | 1.5 Gb

The Altair HyperWorks product team is pleased to announce the availability of Feko and WinProp 2019.2 is a comprehensive computational electromagnetics (CEM) code used widely in the telecommunications, automobile, space and defense industries.

        The most notable extensions to Feko and WinProp in the 2019.2 release.

Salient Features in Feko
- Significant improvements are included in the 2019.2 release that bring about better performanceand a reduction in memory requirements for multiple solution methods. The multilevel fastmultipole method (MLFMM) solution method boasts matrix fill times that are three or more timesfaster by utilising an efficient matrix fill strategy. The parallel scaling of the MLFMM is improvedthrough reduced communication between processes, with the effect becoming more pronounced asthe number of processes increase. Aperture to spherical mode source transformation is availablefor the MLFMM solution method. The time required to calculate the excitation vector is significantlyreduced when the transformation can be applied. Total run time reductions of 30% to 50%were observed for example models. In addition to the improved performance, the fast far fieldcalculation (employed for the MLFMM and other solution methods) uses 30% less memory thanbefore. Optimisation of the adaptive cross-approximation (ACA) matrix fill stage provides a factortwo improvement in performance. The ray launching geometrical optics (RL-GO) solution methodnow utilises shared memory containers resulting in reduced memory requirements for parallelsimulations. A change to the ray storage strategy that avoids duplication of information greatlyreduces the size of the .bof output file and also improves the performance of the RL-GO when theoption to store the rays for processing in POSTFEKO is enabled.
-  Model decomposition is made easier with the new Cartesian boundary near field request. Therequest is defined by points on the surface of a cube (no points are calculated inside the cubevolume) and the surface can then be used as an aperture source in subsequent models. Therequest also allows the user to exclude one or more of the surfaces where the field is known to bezero, such as on a PEC ground plane. The workflow is considerably simplified compared to definingthe rectangular surfaces manually and then ensuring that all the surfaces are correctly positionedand oriented to form the aperture source.
- The finite element method (FEM) solution method is extended to allow transmission lines and non-radiating networks that connect to different FEM ports. Previously the networks could be defined ona single FEM port, but connecting different FEM ports together was not supported. Feed structuresand filters (circuits) can now be connected to the FEM model. These complex FEM componentscan be used in a larger MLFMM model, improving the MLFMM convergence by encapsulating thecomplex component in the FEM region.
- Two new features are added to the Cartesian surface graph allowing better data representationand evaluation. The surface graph, similar to the 3D view display, interpolates between values toshow continuous results as a smooth surface. A discrete display option is added for cases wherecontinuous results are not applicable. When the aspect ratio of the X and Y axis is important, theaspect ratio can be locked to avoid distortion of the image.
- The voltage controlled voltage source (VCVS) and transformer components are introduced forthe cable schematic editor. These components allow one-directional and bi-directional coupling ofcurrents inside the cable shield to the outside of the cable shield to model the effects of imperfectcable terminations. It is crucial to model the cable terminations precisely to obtain accurateresults. The cable solution is also extended with a circuit crosstalk calculation option that takesthe geometry (installation) into account to determine the cable per-unit-length parameters, butdoes not include 3D field coupling between the harness and the installation. This option is usefulwhen only the terminal voltages and currents are of interest and 3D field coupling effects can bedisregarded.   

This file (  ) lists all extensions and improvements to Feko and  WinProp and also bug fixes that are available in 2019.2 release.

Feko    is a powerful and comprehensive 3D simulation package intended for the analysis of a wide rangeof electromagnetic radiation and scattering problems. Applications include antenna design, antennaplacement, microstrip antennas and circuits, dielectric media, scattering analysis, electromagneticcompatibility studies including cable harness modelling and many more.

WinProp   is the most complete suite of tools in the domain of wireless propagation and radio networkplanning. With applications ranging from satellite to terrestrial, from rural via urban to indoor radiolinks, WinProp's innovative wave propagation models combine accuracy with short computation times.

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.

The PC installation is for 64-bit Microsoft Windows Vista/7/8/8.1/10 or Server 2003/2008/2008R2/2012/2012 R2 running on Intel Pentium/Xeon or AMD Athlon/Opteron or compatible pro-cessors. Windows XP, 98, ME and 2000 are no longer supported.

Depending on the specific installation options and the platform, the Windows installation requiresabout 2.1 GBytes free hard disk space.

Display Settings and Graphics Cards

CADFEKO and POSTFEKO can be used with 256 colours, but a colour setting of at least 16 bitsis recommended. The practical use of CADFEKO and POSTFEKO requires a minimum screenresolution of 1200x1024.

Both CADFEKO and POSTFEKO make use of OpenGL (Open Graphics Library). To take advantageof the OpenGL, you require an OpenGL supported graphics card with an installed driver whichenables usage of the OpenGL functionality.

A properly installed graphics card that supports 3D hardware rendering will result in a significantperformance increase for visualisation.  Note that not all graphics cards support OpenGL at allcolour depths.

CADFEKO and POSTFEKO can be configured to allow accurate rendering on most graphics cards.The rendering options are available on theApplicationmenu.  ClickSettings>Rendering op-tions.  Graphics cards that use software rendering may result in improved, but markedly slowerrendering. Face displacement allows a trade-off between edges appearing broken and supposedlyhidden lines being visible.
