Altair Feko

What is Altair Feko ?

Altair Feko is a comprehensive computational electromagnetic code (EMC) widely used in the telecommunications, automotive, space and defense industries.

Feko is a comprehensive computational electromagnetic software (EMC) widely used in the telecommunications, automotive, aerospace and defense industries. Feko offers multiple frequency and time domain EM solvers under a single license. Hybridization of these methods allows efficient analysis of a broad spectrum of MS problems, including antennas, microtape circuits, RF components and biomedical systems, positioning antennas in electrically large structures, scattering calculation, and electromagnetic compatibility (EMC) investigation. WinProp is a dedicated tool for wave propagation modeling and radio network planning.

Feko also offers customized tools to solve more challenging EM interactions, including dedicated solvers for feature-mode analysis (CMA) and two-way cable coupling. Also included are special formulations for efficient simulation of windshield antennas and integrated antenna assemblies.

Combined with MLFMM and true solver hybridization, Feko is considered a global market leader for antenna positioning analysis.

Benefits

One product, several solvents

Electromagnetic applications vary in complexity and electrical size, and no numerical method is able to handle the entire range efficiently. By offering a selection of different solvers, Feko users can choose the most appropriate method for the problem 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 cases, a single solver may still not be enough to solve a challenging problem. Feko offers the industry-leading hybridization of different solvers, combining beneficial features. This allows for more efficient and accurate analysis of problems at various scales, which are complex and electrically large.

Solver accuracy and performance

Extensive validation (analytical solutions, measurement, cross-validation) of numerical methods and improvements in Feko is performed to ensure the accuracy of our approaches. Solver performance and parallel scale are continuously optimized to achieve leading computational efficiency.

HWU license value

As part of the HyperWorks package, Feko can be used with other products (for example, HyperMesh or HyperStudy) at no extra cost. This is the value of the patented HyperWorks drive licensing scheme.

Specialized Solutions

Feko offers the only commercial CMA solver. In addition, specialized numerical solutions for two-way cable coupling, windscreen antennas and large finite assemblies reduce computational requirements. Model decomposition workflows for classic antenna positioning problems allow an equivalent representation of the transmission/reception antenna. WinProp is used for internal/external wave propagation analysis and radio network planning.

User interface and user experience

Intuitive, easy-to-use user interface designed to simplify key workflows and enrich the user experience.

Technical Support and Training

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