The effort of fast numerical simulation of large scale electromagnetic field analysis

Toshihisa Abe


Electric vehicles and hybrid electric vehicles are common in recent years, and the demands for smaller motors, less loss, and less noise are also rising.
As a result, the need to unravel the specific phenomena in 3D analysis is becoming increasingly important.
However, calculation times take longer with 3D analyses as they require the enlargement of analysis models and for this reason, 3D analyses are not being used for the development of daily products to fully explain specific phenomena.
To overcome this issue, parallelization is attempted to increase speed in electromagnetic field analysis.
This presentation will report on calculation speed using 320 parallels in distributed memory-type parallelization.
