■Coupled Analysis (Dynamic Magnetic Field + Heat Conduction) EDDYjω & THERMO
PHOTO-EDDYjω & THERMO
This is a software for coupled analysis of magnetic fields/magnetic fields and heat conduction using the finite element method, performing static analysis and frequency response analysis.
This is a software for coupled analysis of magnetic fields/magnetic fields and heat conduction using the finite element method, capable of performing static analysis and frequency response analysis. It can handle three-dimensional, two-dimensional, and axisymmetric problems. ■□■Features■□■ ■Since it is integrated with the PHOTO series dedicated pre- and post-processing, data creation, analysis, and result processing can be performed as a series of operations. ■A revolutionary speed-up 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 finite element method ensures stable solutions, making it user-friendly even for beginners. ■Since EDDYjω (magnetic field analysis module) and THERMO (heat conduction analysis module) are integrated, the transfer of heat generation density is executed automatically without the need for files. ■It is also possible to use EDDYjω and THERMO independently.

basic information
■ It is possible to conduct analyses that consider the temperature dependence of relative permeability and electrical conductivity at each time step in thermal conduction analysis. (Strong coupling) ■ Linear, nonlinear, and anisotropic permeability can be considered. ■ Analyses that take into account linear and anisotropic electrical conductivity can be performed. ■ The temperature dependence of permeability and electrical conductivity can be considered. (3D) ■ Nonlinear analyses with temperature-dependent thermal conductivity and specific heat can be conducted. ■ Electromagnetic forces acting on magnetic materials and currents are calculated using Maxwell's stress, Lorentz force, and nodal force methods. ■ The sliding interface allows for the handling of objects that move relative to each other. ■ Analyses that consider eddy currents generated in conductors within a varying magnetic field can be performed. ■ The influence of the skin effect on the primary side current can be taken into account. ■ The skin layer creation function allows for easy creation of skin meshes. ■ For other functions and details, please download the catalog or contact us.

Company information
At Photon, we are developing "electromagnetic field analysis software" that models and simulates products and components utilizing electromagnetic phenomena on computers. In traditional design and development environments, the process has primarily revolved around trial and error through prototypes based on the experience of engineers and experiments with those prototypes. However, conducting experiments with actual prototypes and analyzing the results requires significant time and cost. Moving forward, transitioning from an experimental and prototype-based approach to an analysis-based design is a critical issue for improving productivity, and establishing simulation technology as the core of analysis-based design techniques is a challenge. 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 reduce the number of prototypes and development costs, shorten development periods in the manufacturing sites of our users, and ultimately support the enhancement of our users' competitiveness.
