JMAG Case Study
Market: CAE
The greatest value of the Spatial SDKs lies in having established a development framework that allows us to focus on enhancing JMAG’s core value. As a result, JMAG’s simulation engine has evolved to a level that significantly surpasses its competitors in terms of processing performance.
The Company
JSOL CORPORATION was established in 2006 as a spin-off from the Japan Research Institute, and celebrates its 20th anniversary in 2026. Its origins trace back to Japan Information Service Co., Ltd., founded in 1969 as an affiliate of Sumitomo Bank, which later evolved into the Japan Research Institute. Since 2009, JSOL has been jointly owned by NTT DATA and the Japan Research Institute, and operates in both IT and CAE fields. One of its flagship solutions is the electromagnetic field analysis software JMAG.
JSOL’s electromagnetic field analysis software, JMAG, integrates engineering knowledge with advanced simulation technologies to accelerate development and improve performance in the design of electric devices such as motors and transformers. Particularly in the automotive industry, where improving efficiency, cost, and performance are critical, JMAG provides robust support for entire development process from initial design to final product commercialization, earning high trust from manufacturers both in Japan and abroad.
The Challenge
Internal Development Effort for Supporting 3D Geometry Handling Pulls Time and Focus from Core Competencies
JMAG faced the challenge of determining how much internal development effort should be devoted to supporting 3D geometry handling. As JMAG is a CAE simulation software specializing in electromagnetic field analysis—and 3D CADbased design has become mainstream—enhancing 3D modeling capabilities was essential. However, building a complete geometric processing infrastructure in-house was not feasible, and the adoption of reliable and scalable thirdparty libraries became necessary.
Additionally, JMAG users utilize a wide range of CAD software. This diversity required JMAG to support the reliable import of CAD data across multiple formats. 3D InterOp, a robust translator was essential, especially as CAD systems are updated annually, which imposes continuous development burdens.
Key Insights
One stop 3D SDK Provider - Accelerating JMAG Development By Up to 10 Years
Spatial provides a one-stop solution for the SDKs required for 3D geometry processing, which has significantly improved the development efficiency of JMAG. As a result, it has been evaluated that the development period could be shortened by approximately 5 to 10 years compared to in-house development. Furthermore, many functions made possible directly through Spatial SDKs have become vital components that underpin the value of JMAG.
Local Expertise and Continuous Post-Implementation Services is part of recipe for development success
Having Japanese engineers as the primary point of contact enables seamless communication without time zone constraints. The face-to-face meetings and the presence of a dedicated local support system offer trust, ensuring reliable and continuous support even after implementation
Foundational SDKs Illuminate the Future of JMAG
In future product development for JMAG, the JSOL team aims to accelerate the design process by incorporating simulation, utilizing not only geometric information from CAD but also design details such as dimensional constraints and various feature parameters. Additionally, by seamlessly integrating design proposals generated in JMAG with the CAD environment, JSOL aims to enhance the entire workflow—from electrical device design through to manufacturing—making it more efficient.
