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.
