We perform static analysis and transient response analysis using finite element method-based electric field analysis software (electric field simulator).
The software for electric field analysis using the finite element method (electric field simulator) performs static analysis and transient response analysis. It can handle 3D, 2D, and axisymmetric problems. - Since it is integrated with the PHOTO series dedicated pre- and post-processing tools, data creation, analysis, and result processing can be performed as a series of operations. - Because it is integrated with other PHOTO series modules, coupled analysis, such as calculating temperature distribution from heat generation obtained through electric field analysis, can be easily performed. - A revolutionary speedup has been achieved through the combined use of edge element method and ICCG method (tens of times faster than conventional finite element methods). - The use of the finite element method ensures stable solutions, making it safe for beginners to use. - It can be coupled with the thermal conduction analysis module PHOTO-THERMO to calculate temperature distribution from Joule heating within conductors. - Since VOLT and THERMO are integrated, the transfer of heat generation density is automatically executed without the need for files. - It is also possible to use VOLT and THERMO independently.

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.
