Comparison under three conditions: FEM, external field coils, and measurement values! Analysis with the coils moved was also conducted.
We will introduce the analysis results when using coils and external field coils with the finite element method (FEM) for the same analysis target. We adopted "Team Workshop Problem 7," which involves placing a coil on a perforated conductor. Since this problem has measurement values, we compared the results under three conditions: FEM, external field coil, and measurement values, and we also conducted analyses with the coil moved. In the results of the external field and FEM, the graphs overlapped, and the comparison with the measurement values was also favorable. 【Case Overview】 ■ Software Used: PHOTO-EDDYjω ■ Analysis Conditions ・Frequency: 200 [Hz] ・Current Value: 2742 [AT] ・Electrical Conductivity of Conductor: 3.526×10^7 [S/m] ■ Results of External Field and FEM: The graphs overlapped, and the comparison with measurement values was also favorable. *For more details, please refer to the related links or feel free to contact us.

Company information
At Photon, we are developing "electromagnetic field analysis software" that models and simulates products and components utilizing electromagnetic phenomena on a computer. In traditional design and development environments, the process has primarily revolved around trial and error through prototyping based on the experience of engineers and experiments with prototypes. However, conducting experiments using actual prototypes and analyzing the results requires significant time and cost. Moving forward, transitioning from an experimental and prototyping-based approach to an analysis-based design approach will be a crucial challenge for improving productivity, and establishing simulation technology as the core of analysis-based design techniques will be essential. In this context, Photon is developing and providing "analysis software" focusing on electromagnetic fields, as well as heat, vibration, and sound fields. By utilizing Photon's software, efficient development and design of various industrial products can be achieved. In this way, Photon aims to support users in reducing the number of prototypes, lowering development costs, and shortening development periods in their manufacturing environments, ultimately enhancing their competitiveness.
