Simcenter low-frequency electromagnetic solutions allow you to explore designs to meet performance, and make timely-decisions in product development, reducing the number of physical prototypes. The flexibility in our solutions, which includes finite element static, time-harmonic, transient solvers with the motion for any number of components, permits the design and analysis of electromagnetic and electromechanical devices of any complexity.

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.

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.

MoM solves the Maxwell equations in a discrete form without making any approximation: the problem is discretized and transformed into a system of linear equations. Both standard (direct) and fast (iterative with Multilevel Fast Multipole Algorithm) solution approach is available. Different boundary conditions are managed: Electric Field Integral Equation (EFIE), Impedance Boundary Conditions (IBC), Combined Field Integral Equation (CFIE) and, Poggio-Miller-Chang-Harrington-Wu-Tsai (PMCHWT).

Preconditioners (e.g. Multi-Resolution, SPLU, ILUT) speed up the convergence of the iterative solution approach. Low-frequency stabilization methods (S-PEEC formulation) solves the Low-Frequency Breakdown problem (very ill-conditioned linear system). The multi-port approach minimizes the computational burden for the evaluation of active solutions. MoM is suitable in case accuracy is needed for complex problems (in terms of geometries and materials) and when the interaction between the radiation source and the scattering structure is strong.

Complete design and analysis software for permanent magnet, induction, synchronous, electronically and brush-commutated machines. Leverage the fast nature of equivalent circuits and the accuracy of FEA, with the synergy of automating the nonproductive tasks for rapid and accurate analysis of electric machines.

Using a template-based interface makes it easy to use and flexible enough to handle practically any motor topology, with provision for custom rotors and stators. Typical FEA operations such as mesh and solver refinements, winding design, motion, and post-processing, including the export of 1D models, are not required as the software handles these for the user. Performance parameters, waveforms, and field plots are available with just a click.

The Uniform Theory of Diffraction (UTD) is a “ray” method, based on an asymptotic solution of the Maxwell equations. UTD is applicable when a radiating source interacts with a scattering structure whose dimensions are much larger than the field wavelength (e.g., ships, vehicles, or scenario configurations, like airports, factories, cities, etc.). Under these hypotheses, similarly to the optics case, the electromagnetic scattering can be described as the combination of discrete contributions (reflections and diffractions of different orders) from a number of “hot points” distributed on the structure (edge, wedge, vertex) according to relatively simple geometric laws relating to the propagation of rays. UTD manages real materials characterized through transmission and reflection coefficients.
