ANSYS Maxwell is the premier electromagnetic field simulation software for engineers tasked with designing and analyzing 3-D and 2-D electromagnetic and electromechanical devices. Engineers depend on Maxwell to accurately design all types of industrial devices including motors, actuators, transformers, MRI coils, sensors, power supplies and other low frequency devices. These components are being used in new and diverse applications such as automotive hybrid-electric drivetrains, aerospace fault-tolerant electric power systems, alternative energy power generation systems and medical devices. Manufacturers are under pressure to produce smaller, less expensive devices with high reliability and efficiency. Maxwell's industry-leading field-solver technology delivers the power and capability to support the design of these devices.

Maxwell includes solvers for all types of low frequency electromagnetic and electromechanical designs. It includes 3-D/2-D magnetic transient, AC electromagnetic, magnetostatic, electrostatic, DC conduction and electric transient solvers that accurately solve for field parameters such as force, torque, capacitance, inductance, resistance, and impedance. Additionally, Maxwell can automatically generate both nonlinear equivalent circuits and state-space models from the field parameters that may be further utilized in system and circuit simulation analysis. This provides engineers the ability to perform a comprehensive analysis of the component with its drive circuit, loads and other system parameters.

 

Product Features Include:

Automatic Adaptive Meshing

A key benefit of ANSYS Maxwell is its automatic adaptive meshing techniques where users are only required to specify geometry, material properties and the desired output. This meshing process uses a highly robust volumetric meshing (TAU) technique and includes multi-threading capability that reduces the amount of memory used and speeds the simulation time. This proven technology eliminates the complexity of building and refining a finite element mesh and makes advanced numerical analysis practical for all levels of your organization.

Dynamic Link with Simplorer

A key feature in Maxwell is the ability to generate high-fidelity, reduced order models from the finite-element solution for use in Simplorer, the multi-domain system simulation software from ANSYS. The ability to dynamically link Maxwell to Simplorer using reduced order models or alternatively to perform co-simulation between the Maxwell transient solver and Simplorer provides engineers with powerful, electromagnetic-based simulation environment. Engineers can incorporate the design of an electromechanical component with the power electronics to achieve an optimal performing system. This approach allows engineers to utilize simulation techniques to create virtual models of critical components including electrical machines, IGBTs, controls, and characterize (L, R, C) of cables and bus bars that connect these components. By integrating high-fidelity electromagnetic and electromechanical physics-based models into a system-level simulation, engineers can easily optimize drive performance as well as control harmonics and mitigate conducted and radiated EMI/EMC.


Maxwell can be dynamically linked to ANSYS Simplorer to accurately represent the component physics in a circuit and system simulation.

Multiphysics

Maxwell is available as a product within ANSYSWorkbench, the framework upon which the industry's broadest and deepest suite of advanced engineering simulation technology is built. An innovative project schematic view ties together the entire simulation process, guiding the user through complex multiphysics analyses with drag-and-drop simplicity. ANSYS Workbench provides the ability to share geometry, geometry parameters and material properties between the ANSYS product portfolio and Maxwell to solve electromagnetic-thermal-deformation problems.

Multiphysics coupling

  • Electromagnetic -structural with deformed mesh feedback
  • Electromagnetic - CFD
  • Electromagnetic - mechanical - CFD

Maxwell can be linked through ANSYS Workbench to ANSYS Fluent and ANSYS Mechanical to perform electromagnetic-fluid-structural analysis

High-Performance Computing

Maxwell can leverage today's high-powered computers with multiprocessing and distributed analysis options for fast turnaround of your largest designs. The multi-processing option is used for solving models on a single machine with multiple processors or multiple cores which share RAM. The distributed solve option allows users to distribute parametric studies across a number of machines to expedite total simulation time.

Temperature Dependent Permanent Magnets

Maxwell's demagnetization analysis features allow you to study the permanent magnet demagnetization characteristics extended into the third quadrant. External magnetic fields and heating can alter the magnetic properties of hard magnetic materials leading to demagnetization. We can combine these effects to accurately determine the performance of the machine.

Post-Processing

Maxwell provides powerful post-processing features to visualize, animate and report the results of your simulation.

  • Field visualization and animations (shaded, contour and vector plots)
  • Mesh visualization (full, partial)
  • Current, induced voltage, flux linkage
  • Power loss, stored energy
  • Core loss, eddy, excess, hysteresis loss (including the minor loop effects)
  • Impedance, inductance, capacitance
  • Force, torque
  • Custom reports of user-defined solution data

CAD Import

Using AnsoftLinks for MCAD or ANSYS Workbench, Maxwell can import 3-D geometry from mechanical CAD (MCAD) including IGES, STEP, ACIS, Parasolid®, NASTRAN®, Pro/ENGINEER®, AutoCAD®, CATIA®, and Siemens NX™. Maxwell can bi-directionally share geometry, geometry parameters and material properties with other ANSYS solvers. This powerful functionality enables you to easily perform multiphysics simulations.
