Feko 2022.0.2 Release Notes
The most notable extensions and improvements to Feko are listed by component.
CADFEKO
Resolved Issues
– Resolved an issue with the handling of cable loads in models with multiple configurations. Additional (unrequested) load results could sometimes be available in POSTFEKO due to loads not being cleared correctly between configurations.
– Avoid creating zero volume tetrahedral mesh elements in models with symmetry.
POSTFEKO
Resolved Issue
Resolved several issues with the handling of filenames containing multiple full stops (periods).
– POSTFEKO session files containing multiple full stops can now be saved through the API.
– Error and warning messages are corrected to reference the complete filename.
– The specified filename is now used in full when exporting currents or near field results
Solver
Feature
– Significantly improve memory usage when activating ray export for the RL-GO.
Resolved Issues
– When interrupting a simulation on Windows by pressing Ctrl+C, orphan solver processes will no longer remain and licenses will be released correctly.
– Resolved the problem that licenses were not checked back in upon cancellation of a parallel Feko run, resulting in an incorrect accumulation of checked out units in subsequent runs. This was caused by a regression in Feko 2022.
– An error resulting in higher memory usage than expected for MLFMM has been resolved.
– Resolved an error in a model with cable harnesses having multiple configurations.
– An informative error message is now issued for cases where the orientation of cable segments, relative to nearby geometry, may be problematic during the solution.
– The processing of receiving antennas in wideband simulations using asymptotic solvers has been optimized. This will result in faster overall simulation times.
– Resolved an internal error during geometry processing of a VEP model with metallic faces.
Shared Interface Changes
Features
– Added the Create Frequency Ranges macro to create sub-models in a directory for each frequency range specified. A specific solver (MoM, MLFMM, ACA) can be assigned to each frequency range to optimise run time. Use the Combine Results macro in POSTFEKO to merge the results across the different frequency ranges.
– Updated the Optimise model in HyperStudy macro to automatically create a HyperStudy session with the Feko model, solver, variables and output data sources set up in the session.
Support Components
Resolved Issues
– Removed the incorrect unit displayed for the XPR axis for the MIMO Performance Evaluation application macro.
WinProp 2022.0.2 Release Notes
The most notable extensions and improvements to WinProp are listed by component.
ProMan
Feature
– Improved the behavior of the window scroll when deleting a site or antenna in a long list. Now the window cursor stays where the deleted site or antenna was, instead of scrolling to the top of the list.
– Added support for time-variant predictions, in point mode, in a static indoor database.
– Added a new transmitter type, the repeater. This enables simulation of an important class of communication scenarios in which a signal reaches its destination via single or multiple "hops".
– The consideration of propagation phenomena, such as reflection, diffraction, transmission and scattering, of different materials in a database can now be set or modified in ProMan. In previous releases, such changes were only possible in WallMan.
Resolved Issues
– Improved the robustness of duplicate ray detection during IRT predictions.
– Resolved a bug that resulted in a crash when simulating a time-variant project with multiple prediction heights using IRT.
– Fixed a bug that prevented the use of the parabolic equation solver.
– Resolved potential inaccuracies in point mode results due to numerical precision issues.
– The combination of time-variant simulation and trajectory mode is no longer allowed, unless all dynamics along the trajectory are zero.
WallMan
Feature
– Improved .gml database conversion to the WinProp indoor and outdoor binary formats.
AMan
Resolved Issue
– Increased the number of input files that can be converted to beam and envelope patterns to more than 500.
Application Programming Interface
Features
– Site ID related network planning results, such as cell area and number of receiving sites, can now be computed with the WinProp API.
Resolved Issues
– Resolved a bug that resulted in a crash during OFDM network planning predictions of a project, with prediction planes, simulated with the API. Additionally corrected the used transmitter power, in the API, for a project with a transmitter set to non-EIRP mode.
newFASANT 2022.0.2 Release Notes
The most notable extensions and improvements to newFASANT are listed by component.
Solver
Resolved Issue
– Resolved a slowdown with the hybrid MPI/OpenMP simulations when using the MoM module
Feko is a comprehensive computational electromagnetics (CEM) softwareproduct used widely in the telecommunications, automotive, aerospace and defense industries.
The name Feko is an abbreviation derived from the German phrase "FEldberechnung bei Körpern mit beliebiger Oberfläche" (field computations involving bodies of arbitrary shape). As the name suggests, Feko can be used for various types of electromagnetic field analyses involving objects of arbitrary shapes. Feko offers several frequency domain electromagnetic (EM) solution methods as well as a time domain method under a single license. Hybridisation of these methods enables efficient analysis of a broad spectrum of EM problems, including antennas, microstrip circuits, radio frequency (RF) components and biomedical systems, the placement of antennas on electrically large structures, the calculation of scattering (RCS), as well as the investigation of electromagnetic compatibility (EMC).
Feko offers tools that are tailored to solve the more challenging EM interactions, including dedicated solvers for characteristic mode analysis (CMA) and bi-directional cables coupling. Special formulations are included for efficient simulation of integrated windscreen antennas and antenna arrays.
Combined with the multilevel fast multipole method (MLFMM), and true hybridisation of the solvers, Feko is considered the global market leader for antenna placement analysis.
