Motor Design

Motor Design

Altair FluxMotor™ is dedicated to the simulation-driven design of electric rotating machines. It enables users to build from standard or customized parts, add windings, and change materials to quickly develop a concept design. Then, with the power of the Altair Flux™ solver, users can run a selection of tests, try different configurations, compare results, and optimize performance within an intuitive interface specific to motor development.

Antenna Design and Placement

Antenna Design and Placement

Altair Feko™ is widely used in the design of radio and TV, wireless, cellular, communication, remote keyless entry, tire pressure monitoring, satellite positioning, radars, RFID, and other antennas. The Feko® method of moments (MoM) solver is used for antenna design. Model decomposition is possible with accelerated full-wave methods like multi-level fast multipole method (MLFMM), or asymptotic methods like physical optics (PO), ray launching geometrical optics (RL-GO) or Uniform Theory of Diffraction (UTD).

Wave Propagation

Wave Propagation

Feko is a leading tool for wireless propagation modeling and radio network planning for broadcast, cellular, WiFi, and other applications. It includes highly accurate, fast empirical, semi-empirical, rigorous 3D ray tracing models, plus the unique dominant path model (DPM). It simulates a wide range of scenarios, including rural, urban, indoor, and vehicular. This enables simulated radiation patterns of new antenna designs to be evaluated in a network context.

Electromechanical Machines

Electromechanical Machines

Flux models even the most complex electromechanical systems with proven accuracy. It provides multiphysics capabilities – magneto static, steady-state, and transient conditions, along with electrical and thermal properties – to optimize machine performance, efficiency, dimensions, cost, and weight. Flux can model rotating machines with 2D, skew, or 3D representations. It is used in the development of many sensors and actuators, in addition to high-power electrical equipment including transformers, insulator, power bars, and circuit breakers.

Electromagnetic compatibility and electromagnetic interference

EMC and EMI

Electromagnetic compatibility (EMC) and electromagnetic interference (EMI) have become key topics with the proliferation of connected devices, both for component integration and satisfying EMC regulatory requirements. Flux can evaluate the magnetic field radiated by power cables and busbars, and the effect of external fields on the operation of sensors or actuators. Feko can simulate both the radiation and irradiation of cables, antennas, and devices to inform the design of effective shielding.

Bio-Electromagnetics

Bio-Electromagnetics

Feko provides insight into the interactions of electromagnetic fields inside or close to the body. Feko offers a database of human body models to simulate applications including mobile and wireless devices, hearing aids, magnetic resonance imaging (MRI), and medical implants. Analysis of biological tissue ensures that enough signal is radiated while complying with regulations that limit the specific absorption rate (SAR) and the temperature increase in the body.
