Simcenter MAGNET is a powerful electromagnetic field simulation solution for performance prediction of motors, generators, sensors, transformers, actuators, solenoids or any component with permanent magnets or coils.

**Model the physics of electromagnetic devices**

Simcenter MAGNET includes capabilities to accurately model the physics of electromagnetic devices. This includes the ability to model manufacturing processes, temperature dependent material properties, magnetization and de-magnetization modeling, and vector hysteresis models among others.

Simcenter MAGNET also has a built-in motion solver with a six degree-of-freedom capability. It allows for complex problems like magnetic levitation or complex motion to be accurately modeled and analyzed. This is made possible with a unique smart re-meshing technology.

**Explore the possibilities through simulation automation**

An efficient design process requires tools which can be customized to the workflow. Simcenter MAGNET includes sophisticated scripting capabilities that allow for flexible workflow automation.

Using the Simcenter MAGNET fully parameterized CAD functionality will improve the efficiency of your simulation. In particular, models that would ordinarily require a lot of manual processes, such as those that include numerous calculations for various magnets with different dimensions and many air gaps.

**Stay integrated with circuit to system level modeling**

System-level (1D) or model-based (2D axisymmetric, 2D translational, and full 3D) analysis requires accurate sub-component models to account for interactions and local transients that affect the overall system behavior.

Simcenter MAGNET includes capabilities such as native circuit simulations, connections for co-simulation and exporting of 1D system models for Simcenter Flomaster, Simcenter Amesim and other platforms.

skyTran leverages Simcenter MAGNET to reduce physical prototyping time and costs by 90 percent for its maglev system.

AC electromagnetic simulations are based on a single frequency, which reduces the simulation time. With this approach, you can simulate electromagnetic fields in and around current-carrying conductors, in the presence of isotropic materials that may be conducting, magnetic or both. This accounts for displacement currents, eddy-current and proximity effects, which are important in hotspot analysis.

The accuracy of low-frequency electromagnetic simulations is highly dependent on material data. Simcenter electromagnetic advanced material modeling accounts for nonlinearities, temperature dependencies, demagnetization of permanent magnets, hysteresis loss and anisotropic effects. This makes it possible to analyze effects such as demagnetization in permanent magnets to verify their service life, analyze frequency dependent losses in thin parts while reducing solution time, and account for all losses for an accurate energy balance.

The finite element method for electric fields can be used to simulate static electric fields, AC electric fields and transient electric fields. It can also simulate current flow which is the static current densities produced by DC voltages on electrodes in contact with conducting materials.

Electric field simulations are typically used for high-voltage applications to predict insulation and winding failures, lightning impulse simulations, partial discharge analysis and impedance analysis.

The electromagnetic simulation of transient fields can include motion. It is possible to simulate rotational, linear and arbitrary motion with six degrees of freedom (X, Y, Z, Roll, Pitch and Yaw). This is available for an unlimited number of moving components, induced currents and mechanical interactions.

The mechanical effects include viscous friction, inertia, mass, springs and gravitation, as well as constraints on movement imposed by mechanical stops. Arbitrary load forces can be specified as a function of position, speed and time. Induced currents due to motion are taken into account.

Permits the simulation of complex problems that involve time-varying arbitrary-shaped current or voltage sources and outputs with nonlinearity in materials and frequency-dependent effects. This includes oscillations in electromechanical devices, demagnetization in permanent magnets, switching effects, eddy-currents induced torque, skin and proximity effects. Furthermore, by using the Simcenter MAGNET thermal solver you can couple your thermal-electromagnetic in a co-simulation.

The thermal and electromagnetic modules of Simcenter MAGNET can be used to simulate steady-state and transient temperature distribution, considering losses in the windings as well as the core, including the eddy current and hysteresis losses. The Simcenter MAGNET thermal solver uses finite elements to quickly evaluate the thermal performance of your electric device.
