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.

Simcenter comes with a wide range of models to address a range of electromagnetics simulations. Models include Finite Volume (FV) 2D, FV 2D axisymmetric, FV 3D and Finite Element (FE) 3D for applications ranging from magnetic valves, solenoids, actuators, transformer, electric machines. Magnetohydrodynamics (MHD) applications including plasma arc simulation, gas-blast circuit breakers and welding can also be optimized with the 2D FV MHD solver. Harmonic Balance solver expands application coverage for axisymmetric and 3D FV solvers by avoiding the need to co-simulate coupled frequency/time domain problems.

Iterative Physical Optics (IPO) is a current -based iterative high-frequency technique. IPO is applicable in the evaluation of the interaction between a radiating source and a scattering structure whose dimensions are larger than the field wavelength (e.g. antenna reflectors, radomes, vehicles, etc). The application of the equivalence theorem for the description of the scattering mechanism and adoption of the iterative process allows the reconstruction of the interactions between objects in complex scenarios without resorting to ray-tracing. The computational capabilities are optimized by exploiting of cutting edge technologies: GPU computing, Fast Far-Field Approximation algorithm, and iterative relaxation techniques. Thin sheet and impedance boundary conditions formulations are available.

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.
