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

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

ANSYS Electronic HPC enables full parallelization, multicore support with shared memory for ANSYS Maxwell 3-D transient simulations. The HPC functionality adds multithreading technology that speeds initial mesh generation, direct and iterative matrix solves, and field recovery for these computationally intensive simulations.
Distributed Computation of Parametric Electromagnetic Field Simulation
Distributed solve is an option for ANSYS Maxwell that delivers the power of distributed computing to maximize overall productivity. With distributed solve, Maxwell can distribute parametric studies across available hardware to expedite EM model extraction, characterization and optimization.
Distributed solve allows a single user to distribute parametric studies or frequency points across a number of machines to expedite total simulation time. This time-saving capability splits multiple predefined parametric design variations and/or frequency points, solves each simulation instance on a separate machine, and then reassembles the data. The functionality dramatically accelerates parametric studies and design optimization.
Vector hysteresis behavior obeys the following properties:
- Rotational symmetry
- Rotational loss
Applicable to both hard and soft magnetic materials
No model parameters identification required
Only input ascending (or descending) limiting B(H) curve required
No significant computation time increase compared with single nonlinear scalar behavior
Efficient memory management
ANSYS Maxwell's demagnetization analysis features allow you to study 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.
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
- Field post processing on nonmodel sheet object
- Field overlay plot markeR
- Export and post-process field in cylindrical and spherical coordinate system
- Allow nonmodel moving objects
- Export field solution at mesh node for user control program access
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 bidirectionally share geometry, geometry parameters and material properties with other ANSYS solvers. This powerful functionality enables you to easily perform multiphysics simulations.
