Product Features
New Time Domain Solver
With Maxwell, you can precisely characterize the nonlinear, transient motion of electromechanical components and their effects on the drive circuit and control system design. By leveraging Maxwell’s advanced electromagnetic field solvers and seamlessly linking them to the integrated circuit and systems simulation technology.
PExprt
Power Electronics Expert (PExprt) is a magnetic design and optimization tool for ferrite transformers and inductors including, multi-winding transformers, coupled inductors, and flyback components. PExprt’s template-based interface for transformers and inductors can automatically create a design from voltage waveform or converter inputs. The auto-design process considers all combinations of core shapes, sizes, materials.
Simplorer
A multi-domain power electronics simulator for electrical, magnetic, mechanical, fluid, and thermal systems that seamlessly integrates three fundamental component libraries: circuits, block diagrams, and state machines. Simplorer provides an integrated analysis thanks to its connection with EM (Maxwell, PExprt, RMxprt, Q3D, HFSS) and thermal tools (Ansys CFD, Ansys Icepak).
RMxprt
In addition to providing classical motor performance calculations, RMxprt automatically generates geometry, motion and mechanical setup, material properties, core loss, winding and source setup for detailed finite element analysis in Maxwell.
Specialized Design Interfaces
Electric machines and power converters require significantly different design criteria and simulation, which is why Maxwell provides specialized interfaces for each.
Advanced Magnetic Modeling
Perform advanced simulation calculations such as core loss calculations, vector hysteresis, four-quadrant simulation for permanent magnets, magnetostriction and magnetoelastic analysis, Litz Wire Loss and manufacturing effects on loss computation.
Automatic, Adaptive Meshing
A key benefit of Maxwell is its automatic adaptive meshing techniques, which require you to specify only the geometry, material properties and the desired output to obtain an accurate solution. Maxwell’s meshing process uses a highly robust volumetric meshing technique and includes a multithreading capability
Multiphysics Coupling Workflow
Maxwell’s electromagnetic field solvers are linked through Ansys Workbench to easily set up and analyze complex coupled-physics behaviors such as deformed mesh feedback structures, stress and strain feedback on magnetic properties, EM fluids and acoustics.
MODULES
Low-Frequency Electromagnetic Simulation
With Maxwell, you can precisely characterize the nonlinear, transient motion of electromechanical components and their effects on the drive circuit and control system design. By leveraging Maxwell’s advanced electromagnetic field solvers and seamlessly linking them to the integrated circuit and systems simulation technology, you can understand the performance of electromechanical systems long before building a prototype in hardware.
Slice-only Technology
Slice-only technology enables a cyclic repeatability simulation technique for electric motor applications. The analysis has been improved by efficiently solving just a slice of the motor, employing non-planar boundary conditions, using symmetric mesh and replicating results to the full model.

How to assign matrix parameters in Ansys Maxwell?
To solve for a capacitance, inductance, impedance, or conductance matrix:
Click Maxwell 3D or Maxwell 2D, and then select Parameters>Assign>Matrix.
The Matrix dialog box appears.
Click the Setup tab.
Type a name for the matrix in the Name box.
To specify the sources to be included in the matrix, do one of the following:
For 3D Electrostatic, 2D and 3D Magnetostatic, 2D and 3D Eddy Current designs, select or clear the Include check box for any of the listed sources.
For Maxwell 2D designs, the return path for each source may be specified. By default, the return path is at infinity; however, any conductor with a source specified can act as the return path.
For 2D Electrostatic, 2D and 3D DC Conduction, and 2D and 3D AC Conduction, select or clear the Signal or Ground check box for any of the listed sources. Grounded terminals are treated as reference voltages with zero voltage values.
Excitations checked as Signal will be in the matrix (excited one at a time with 1V during the parameters extraction process). Those excitations checked as Ground will be kept at 0 V and will not be part of the matrix. Any excitations not checked will not be considered.
