In January 2020, JMAG-Designer Ver.19.0 has been released.
JMAG-Designer Ver.19.0 is advanced tools that allow searching a wide design space in a short period of time. In addition, functions such as efficiency maps and zooming analysis of existing functions have been enhanced.
Please enjoy taking full advantage of it.

What is JMAG-Designer Version 19.0 ?

Analysis Parameter View / Dashboard
Advanced tools that allow searching a wide design space in a short period of time. Vary parameters such as for shape, materials, conditions, etc. and perform evaluation in two windows.

Enhancement of Structural Analysis
Added material nonlinearity of structural analysis. It realizes accurate evaluation of stress when yield stress is exceeded. Enhanced contact condition can be taking into account part’s colliding between them.

Topology Optimization
Fast topology optimization method is added. The density method can optimize the topology for a relatively simple problem with a small amount of calculation.

Enhancement of Robustness and Speed of Mesher
Mesher is enhanced, and mesh generation success rate and speed are improved.

Efficiency Map
The efficiency map function of JMAG-Designer has become more useful.

Speed Up for small-scale model
Reduced processing time for non-parallel calculation with small-scale model.

Analysis Parameter View / Dashboard

×

Advanced tools that allow searching a wide design space in a short period of time. Vary parameters such as for shape, materials, conditions, etc. and perform evaluation in two windows.
Setting quickly using analysis parameter view, and quick solving using high speed solver and mesher. Evaluate quickly using dashboard, and can quick feedback to design.

Enhancement of Structural Analysis

×

Added material nonlinearity of structural analysis. It realizes accurate evaluation of stress when yield stress is exceeded. Enhanced contact condition can be taking into account part’s colliding between them.
Stress distribution due to centrifugal force of synchronous reluctance motor. The same result is obtained with JMAG and JOH / NIKE (*).

Topology Optimization

×

Fast topology optimization method is added. The density method can optimize the topology for a relatively simple problem with a small amount of calculation.
Optimization result of magnetic shield by density method. A multi-layer shield shape has been obtained to minimize the magnetic flux density at the evaluation point.

Enhancement of Robustness and Speed of Mesher

×

Mesher is enhanced, and mesh generation success rate and speed are improved.
For complex or large models, the speed is more than doubled compared to V18.0.

Parallel Time Periodic-FEM

×

A steady state results can be obtained by an analysis for one cycle. Moreover, the analysis time can be greatly shortened by parallel calculation.
Parallelization scalability can be obtained by introducing TP-FEM (right). As a result, it is possible to obtain a result by calculating one cycle shorter than the steady state by the TP-EEC method (left).

Speed Up for small-scale model

×

Reduced processing time for non-parallel calculation with small-scale model.
Not only the analysis time, but also the time for job submission processing and result reading are reduced. A particularly high-speed effect can be obtained with a small scale of 10,000 elements or less.

Efficiency Map

×

The efficiency map function of JMAG-Designer has become more useful
Using an efficiency map (Speed Priority), quickly evaluate machine characteristics driven in motor mode / generator mode. And the loss for each part can be displayed.
