Ansys Maxwell Key Features

Since the design specifications and simulation requirements for low-frequency electric machines and power converters are so dissimilar, Ansys Maxwell offers separate interfaces for each.

Ansys Workbench connects Ansys Maxwell’s low-frequency electromagnetic field solvers.  Conveniently, making it simple to set up and analyze complex coupled-physics behaviors.  For example, deformed mesh feedback structures, stress and strain feedback on magnetic properties, EM fluids, and acoustics.

Perform advanced simulation calculations such as core loss calculations, vector hysteresis, four-quadrant simulation for permanent magnets, magnetostriction and magnetoelastic analysis, and loss computation manufacturing effects.

Ansys Maxwell’s automated adaptive meshing techniques, which require only the geometry, material properties, and desired performance to achieve an effective solution, are a key feature.

Highly Reliable Volumetric Meshing

Ansys Maxwell’s meshing method employs a highly reliable volumetric meshing technique as well as multithreading.  In short, this decreases memory use and speeds up time to solution. This tried-and-true technology simplifies the process of creating and refining a finite element mesh.  Ultimately, making advanced numerical analysis accessible to employees at all levels of your business.

RMxprt produces geometry, motion and mechanical setup, material properties, core loss, winding and source setup for comprehensive finite element analysis in Ansys Maxwell, in addition to providing traditional motor output measurements.

The template-based interface for transformers and inductors in RMxprt can generate a configuration automatically based on voltage waveform or converter inputs. To optimize the magnetic configuration, the autodesign process considers all combinations of core shapes, sizes, materials, gaps, wire types and gauges, and winding strategies.
