JMAG-Designer version 10 has implemented and reinforced an expanding palette of features fortifying simulation technology so that the most comprehensive analyses are accessible using simple operations geared toward experienced analysis specialists and engineers just starting to engage in CAE alike. The following examples that include the major modeling, analysis, and linking features are just a glimpse of the new capabilities implemented into JMAG-Designer version 10.4.
Defeaturing
One of the primary examples of the experience required for modeling is knowing how to reduce the scale of a model by simplifying geometry based on the objective of an analysis. Defeaturing simplifies the geometry of mesh models by removing fillets, chamfers, or holes automatically when generating mesh.

Mesh Morphing
The geometry of mesh models can now be manipulated directly. Mesh morphing allows the most accurate results focusing on dimensional variations to be obtained while minimizing error caused by the mesh resulting from small geometrical changes of models.

High-speed Magnet Loss Calculation of Rotation Machines
Examining the eddy currents that occur in the magnets of motors has required a significant amount of time because analyses using a three-dimensional model has been required. The high-speed magnet loss calculation of rotation machines provides the fastest possible analysis.
Conventional methods to calculate the eddy current loss of magnets that require 8 hours can now be run in approximately 12 minutes.

Electric Field Analysis
JMAG-Designer now supports electric field and current distribution analyses. A broad range of phenomena can be analyzed including the static capacitance of capacitors and the stray capacitance of motors. Go even deeper into your design by coupling to a thermal analysis to obtain the heat generation of capacitors and the temperature dependency of the electric properties.

Frozen Permeability
The magnetic flux density distribution and flux lines that isolate the factors making up the phenomena can be evaluated by fixing the magnetic properties of materials in a specific state using the frozen permeability condition to analyze a model.

Achieve Multi-perspective Evaluation via Links to Third-party Programs
An analysis environment capable of examining electromechanical design from multiple perspectives is attained by interactively linking JMAG-Designer to the CAE software for structural and thermal analysis, ABAQUS.

Using JMAG-Studio
Although this article has focused on introducing the functions that have been added and improved in JMAG-Designer, the solver and mesh functions described above have been implemented in JMAG-Studio as well as JMAG-Designer. The output files for both JMAG-Designer and JMAG-Studio are bilaterally compatible, and both systems can be run on the same computer. Even though the quality of JMAG-Studio will continue to improve in the future, please don't hesitate to try JMAG-Designer which offers a new type of framework for analysis technology.
