FEKO is a comprehensive computational electromagnetics (CEM) software used widely in the telecommunications, automobile, aerospace and defense industries. FEKO offers several frequency and time domain EM solvers under a single license. Hybridization of these methods enables the efficient analysis of a broad spectrum of EM problems, including antennas, microstrip circuits, RF components and biomedical systems, the placement of antennas on electrically large structures, the calculation of scattering as well as the investigation of electromagnetic compatibility (EMC). WinProp is a dedicated tool for wave propagation modeling and radio network planning.

FEKO also offers tools that are tailored to solve more challenging EM interactions, including dedicated solvers for characteristic mode analysis (CMA) and bi-directional cables coupling. Special formulations are also included for efficient simulation of integrated windscreen antennas and antenna arrays.

Combined with the MLFMM, and the true hybridization of the solvers, FEKO is considered the global market leader for antenna placement analysis.

“FEKO modelling on the Cape Town CHPC has been pivotal in RFI mitigation research at Stellenbosch University for the MeerKAT Telescope. We have successfully validated dish scale models with measurement and continue to use FEKO to study EM induced current paths and provide RFI mitigation recommendations to SKA South Africa.”

Benefits

One Product, Multiple Solvers

Electromagnetic applications vary in complexity and electrical size and no single numerical method is capable of handling the entire range efficiently. By offering a selection of different solvers, FEKO users can choose the method that is most suitable to the problem that they are trying to solve, or use more than one solver for cross validation purposes. All solvers are included in FEKO, and are not licensed separately.

True Hybridization

In some instances a single solver might still not be enough to solve a challenging problem. FEKO offers industry leading hybridization of different solvers, combining the beneficial characteristics. This allows more efficient and accurate analysis of multi-scale problems, that are both complex and electrically large.

Solver Accuracy and Performance

Extensive validation (analytical solutions, measurement, cross validation) of the numerical methods and enhancements in FEKO is carried out to ensure the accuracy of our approaches. Solver performance and parallel scaling is continually optimized to achieve leading computational efficiency.

HWU License Value

As part of the HyperWorks suite, FEKO can be used with other products (e.g. HyperMesh or HyperStudy) at no extra cost. This is the value of the patented HyperWorks unit licensing scheme.

Specialized Solutions

FEKO offers the only commercial CMA solver. Furthermore, specialized numerical solutions for bidirectional cable coupling, windscreen antennas and large finite arrays reduce computational requirements. Model decomposition workflows for classical antenna placement problems enable equivalent representation of the transmitting/receiving antenna. WinProp is used for indoor/outdoor wave propagation analysis and radio network planning.

User Interface and User Experience

Intuitive and easy to use User Interface designed to simplify main workflows and enrich the user experience.

Technical Support and Training

Excellent local technical support network. Comprehensive and in-depth training sessions can be requested to accelerate the learning curve.
