Electromagnetic Simulation

The diverse and increasingly significant role of electromagnetics in product development and design brings new challenges. In this regard, committing to deliver products that are higher in efficiency, reliability, compatibility, and durability starts with comprehending how these complex fields and waves behave and change.

Simcenter includes distinct low and high-frequency electromagnetic simulation capabilities for the unique demands in each domain. Expand your insight into the performance of electromechanical components, energy conversion, design and siting of antennas, electromagnetic compatibility (EMC) and electromagnetic interference (EMI). A range of dedicated solvers (time and frequency based, linear and nonlinear, finite and boundary element) offers a transformative CAE process, with simulations ranging from a fast, initial analysis to inherent realism for final verification.

Electric Field Analysis


There are three electric field analysis capabilities: Static (produced by DC voltages and charge distributions), AC (produced by AC voltages), and transient (produced by voltages that vary arbitrarily in time). The electric field analysis can also simulate current flow – the static current densities produced by DC voltages on electrodes in contact with conducting material.

The electric field analysis is typically used for high-voltage applications to predict insulation and winding failures, lightning impulse simulations, partial discharge analysis, and transmission tower and lines impedance analysis.

Electromagnetics Multiphysics


Do not design your electromagnetics components in isolation. Include real-world multiphysics phenomena including flow, heat transfer, electrochemistry, solid mechanics and motion to simulate and couple all the necessary physics.

High-Frequency Electromagnetics


Industry 4.0 factories, incorporating wireless IIoT systems, will operate within a complex and noisy electromagnetic environment. There is an increasing number of electronic devices and electric cables and wires in vehicles. There is a growing number of antennas and new types of wireless devices. It is increasingly challenging to ensure a device keeps working properly by being immune and not interfering with the surrounding devices causing possible failure.

Simcenter for high-frequency electromagnetics addresses a wide frequency spectrum to cover all prime analysis needs. Users can select the most appropriate from a range of dedicated solvers. These include full wave solvers based on integral methods for solving Maxwell’s electromagnetic equations (Method of Moments) and asymptotic methods based on the uniform theory of diffraction (UTD) and iterative physical optics (IPO). Efficiently solve for 2.5D as well as for full 3D field problems. Solver acceleration options are embedded to facilitate straightforward handling of ultra-large-scale, system-level models such as full aircraft, satellites, ships, and cars.

Thermal Analysis


Coupled thermal finite element analysis simulates the temperature distribution as a result of heat rise or cooling in the electromechanical device. It seamlessly couples to electromagnetic and electric field simulations, and uses their power loss data as a heat source, and then determines the overall performance due to the impact of temperature changes. This analysis determines the nonlinear steady-state or time-varying temperature distributions caused by the specified heat sources.

Using this analysis, you can predict the temperature distribution caused by ohmic, eddy-current, core and dielectric power losses, and the corresponding temperature effects on material properties and electromagnetic and electric fields. Hence, you can accurately predict the demagnetization of permanent magnets, and hotspots to determine the loading capacity and service life of your device.
