Induction heat treatment has the advantages of low fire risk, low working environment temperature, and reduction of CO2 emissions. Therefore, we are developing induction heat treatment technology and expanding its application. We use induction heating analysis of JMAG for efficient technology development, and shortening the analysis time is important for further accelerating development.
This time, I was able to shorten the analysis time by adopting an AMD CPU, so I will introduce the hardware selection. In addition, I will introduce examples of improving analysis work efficiency by investigating the relationship between the number of elements and parallel computing speed in medium-scale models with less than 1 million elements.
