Frequency response analysis software for dynamic magnetic fields using the finite element method EDDY jω
Perform frequency response analysis Finite element method magnetic field analysis software (magnetic field simulator) ■□■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. ■It is integrated with other PHOTO series modules, allowing for easy coupled analysis, such as deriving temperature distribution from heat generation obtained through electromagnetic field analysis. ■A groundbreaking speedup has been achieved through the combined use of edge element method and ICCG method (dozens of times faster than conventional finite element methods). ■When a sine wave input is used and linear approximation holds, results can be obtained in a single calculation without the need for time-stepping calculations. ■Since it uses the finite element method, the solutions are stable, making it easy for beginners to use with confidence. ■Coupled calculations with thermal conduction analysis, stress analysis, and fluid analysis are easy to perform.

basic information
The software for magnetic field analysis using the finite element method performs frequency response analysis. ■ It can handle three-dimensional, two-dimensional, and axisymmetric problems. ■ Linear, nonlinear, and anisotropic permeability can be considered. ■ Analysis considering linear and nonlinear electrical conductivity is possible. ■ The temperature dependence of permeability and electrical conductivity can be taken into account (3D). ■ Input of currents with multiple phases can be performed. ■ There is an automatic current input function and a voltage input function (3D). ■ Analysis considering eddy currents generated in conductors within a varying magnetic field can be performed. ■ A slide interface allows for the handling of mutually moving objects. ■ As analysis results, magnetic flux density, eddy current distribution, etc., can be obtained as real and imaginary components. Additionally, the Lorentz force is outputted. ■ Using the permeability from files obtained through nonlinear magnetic field analysis with PHOTO-EDDY, analysis considering the nonlinearity of magnetization characteristics can be performed. ■ The types of output analysis results can be controlled. ■ The influence of the skin effect of primary side currents can be considered. ■ 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.
