サイエンスソリューションズ List of Products and Services

Tracing back to the foundations of a wide range of technologies is something that we cannot accomplish on our own. Therefore, we create optimal solutions through partnerships with universities, research institutes, and companies both inside and outside the organization.

EMSolution is an electromagnetic field analysis software that has introduced and improved the edge element finite element method since its early stages. In addition to the introduction of edge elements and the ICCG method, it has independently developed and implemented advanced analysis techniques such as the nodal force method and the sliding method, enabling large-scale and high-precision analyses to be performed quickly.

We have developed the parallel high-speed electromagnetic field analysis solver 'HPC-EMSolution' that "accelerates electromagnetic field analysis by 100 times and analyzes models 10 times larger." Its overwhelming speed and capability to handle large-scale models break the conventional wisdom of electromagnetic field analysis in electrical equipment design, leading to breakthroughs in product development and providing a competitive edge that overwhelms other companies. 【Features】 ■ Significantly reduces analysis time through parallel analysis ■ Enables analysis of large-scale models with tens of millions of elements ■ Improves analysis speed through parallelization ■ Available for immediate use with no initial investment *For more details, please refer to the PDF document or feel free to contact us.

EMSolution-Lite is a budget version of EMSolution (electromagnetic field analysis) specifically designed for two-dimensional analysis. While the analysis model is limited to two dimensions, it allows users to utilize most of EMSolution's features (equivalent to the Professional package) for models with up to 100,000 elements. It was created in response to users' demands for an easy way to perform two-dimensional electromagnetic field analysis. For example, it can perform no-load analysis of PM motors as well as PWM voltage source analysis. Additionally, it can analyze the slip-torque characteristics of induction motors. Circuit and motion coupling analysis for electromagnets and actuators is also possible. We encourage you to use it for two-dimensional analysis and parameter surveys of motors, actuators, and more.

In motor design, the complexity of initial setup and the limited number of trials become a bottleneck for productivity. eMotorSolution completes modeling in just a few minutes with its shape template and winding setting features. The built-in high-speed 2D analysis (EMSolution Lite) allows for rapid iteration of parameter studies. Results are immediately visualized as magnetic flux lines, contours, vectors, and waveforms, and can be smoothly integrated into existing design flows through dxf/CATIA compatibility and Python support.

EMSOptimizer is an optimization framework that provides elements of optimization calculations (objectives, evaluation functions, constraints, and search methods) as classes, allowing for flexible combination through inheritance and implementation in Python. Designed with the premise of introducing OSS optimization libraries, it enables direct application of the latest methods for A/B comparisons and custom improvements in practical work. It integrates shape optimization using the NGnet method and parameter optimization in collaboration with eMotorSolution within the same workflow, balancing research speed and implementation speed. It offers engineers and researchers with experience in optimization and Python the freedom to "immediately apply the latest OSS methods to real-world problems."
