Analysis of two-dimensional axisymmetric and three-dimensional transient response of dynamic magnetic fields using the finite element method, considering motion (Dynamic Magnetic Field Simulator) ■□■Features■□■ ■Since it is integrated with other PHOTO series modules, coupled analysis, such as obtaining temperature distribution from heat generation calculated by electromagnetic field analysis, can be easily performed. ■A revolutionary speedup has been achieved by combining edge element method and ICCG method (dozens of times faster than conventional finite element methods). ■The use of the finite element method ensures stable solutions, making it user-friendly even for beginners. ■By incorporating a slide interface for two-dimensional, axisymmetric, and three-dimensional problems, the motion of objects can be easily handled. ■The motion of objects due to electromagnetic forces can be calculated in real-time by solving the equations of motion.

The analysis case of hinge-type electromagnetic relays requires mesh division of space in the finite element method. Therefore, handling the motion of objects in the finite element method has been considered a very difficult category of analysis, as it necessitates the manipulation of meshes, including spatial meshes. In the PHOTO-Series, we have newly developed a unique analysis function that automatically deforms the spatial mesh into an optimal shape according to the motion of the object, thereby solving this problem.

The "PHOTO series" offers analysis solvers that utilize the most suitable simulation methods for a wide range of target fields, from high-frequency electromagnetic waves to low-frequency electric and magnetic fields, based on the analysis theme. Unlike other commercial software packages that handle all phenomena with a single analysis solver, we use the most appropriate analysis solver for the purpose, ensuring high analysis accuracy and detailed responsiveness to needs. Additionally, you can select only the necessary modules suited to the problem, which helps keep the implementation costs economical. It is also easy to expand functionality by adding modules, and by combining them, it is possible to handle coupled analyses such as heat generation due to eddy currents and stresses or deformations caused by electromagnetic forces. All products are compatible with three-dimensional problems, and the transient response analysis module can handle nonlinear materials.
