ANSYS for Electromagnetics

ANSYS products for Electromagnetics allow electromechanical analyses for characterization of electrical drives, sensors, and transformers, high frequency analyses for describing wave propagation for antennas and electronic assemblies, and for circuit calculations to analyze performance and signals.

Typical applications

Electric motors, valves, and electromagnets are analyzed under real operating conditions. As a result, the torque ripple for motors can be reduced significantly and a mechanical and acoustic load (noise) can be avoided.

In addition to improving field management, you can configure material use for increased efficiency.

Thermal stability and service life can be improved.

You can ensure optimal installation conditions and avoid external interferences.

Product characteristics can be improved, for example with specific switching of contacts and shielding.

You can check the EMC compliance, protect the signal integrity of data transmission applications, and examine the power integrity in order to guarantee a reliable energy supply even at high frequencies.

In addition to increasing signal quality, for example for antennas, filters, and couplers, it is easier to specifically identify and camouflage objects.

NF: Increase the efficiency of an electric drive

HF: antenna simulation

Performance characteristics

ANSYS offers an extensive and expandable library of material models for non-linear, anisotropic, and temperature-dependent material behavior as well as for 3D vector hysteresis. In addition to this are integrated adaptive networking methods for guaranteeing robust results for static and dynamic analyses (Maxwell, HFSS). There is also a user-friendly implemented characterization of movement effects in electromagnetic field functions (rotation, translation, swinging). The functionality is rounded out with extensive, application-optimized element technology (like mixed finite and boundary elements), as well as quickly solving equations in 2D and 3D. Parallel and simultaneous calculation provides high performance computing (HPC).

Predefined processes, for example for rotating electric machines (RMxprt), high-performance electronics (PExprt), or antennas (Antenna Design Kit), to save time and guarantee the greatest possible precision.

By making your own adaptations, you can tailor the CAE system even more specifically to your needs. There are several language standards available to you for this purpose: VHDL-AMS, Modelica, and Python. In addition, you may choose any desired potential formulation for maximum precision and the best possible performance, especially in parameter studies. The embedded calculator additionally provides flexible access to all important integral results.

Matrix and solver linking lets you connect different physical domains. Other features include integrated and automated derivation of behavioral models for system simulations and co-simulation with the ANSYS Simplorer switching simulator and the ANSYS CFD fluid solution.

ANSYS Modules

The following modules, some of which are specialized, are available for the variety of demanding simulation tasks in the area of Electromagnetics:

For simulation of electromagnetic fields with a focus on electric drive technology and power transmission: This module can be combined with the ANSYS RMxprt expert solution for efficient design of rotating machines. The integrated formulations for analyzing moving magnetic systems and for descriptions of eddy currents that are accurate in every detail offer the highest possible degree of performance and flexibility.

High-performance switching simulator for describing tasks: it can be expanded with the ANSYS PExprt expert tool for designing transformers and cores. As part of the interdisciplinary system simulation, ANSYS Simplorer forms the central interface between software and hardware design, with an extensive component library, the option of implementing existing models from VHDL-AMS and Modelica, and comprehensive interfaces with the ANSYS field solvers.

For calculating high-frequency electromagnetic field tasks. This includes emission of electromagnetic waves and the transmission behavior of passive components. The adaptive networking guarantees automatic adaptation of the network used and with it the desired solution quality. High-performance equation solvers for FEM and integral equations in the frequency range as well as transient solvers ensure performance for a wide range of application fields.

For analyzing the transmission and radiation behavior on the circuit board and package level. The specialization in planar structures ensures high performance for the numerical mathematics and the user.

For efficient characterization of parasitic effects with direct data export for system analysis. The focus is placed on packages, cables, conductor rails, or touch screens and allows for fast extraction of behavior models.
