Computational Mechanics Research Center

What Computational Mechanics Research Center does

Computational Mechanics Research Center, Inc. (株式会社計算力学研究センター, RCCM) is a privately held Japanese software company founded in 1987, headquartered in Shinagawa, Tokyo, with a regional branch in Osaka. RCCM develops and sells proprietary numerical analysis software and, in parallel, acts as the exclusive Japanese distributor and technical-support channel for a portfolio of globally leading CAE and simulation products. Its own proprietary products address narrow, standards-driven domains where global majors are underserved: ASTEA MACS for mass-concrete temperature-stress analysis (aligned to JSCE, JCI, and AIJ crack-control guidelines), MECHANICAL FINDER and FEMS for orthopedic biomechanics and bone-strength evaluation, e-River for small-to-medium river maintenance management, and a Deep Eddy Current Sensor for non-destructive testing. In addition, it provides the Japanese market with the FactSage family of chemical-thermodynamic equilibrium products developed by GTT-Technologies (Germany) and VTT (Finland), as well as resold brands spanning Siemens Simcenter (Nastran, FEMAP, 3D, FloEFD, HEEDS), ANSYS products (Fluent, Rocky, Discovery, OptiSLang, EnSight), Autodesk Moldflow, Actran, Solid Edge, LUSAS, and 3DSimSTAMP.

RCCM monetizes through a multi-stream model: one-time perpetual licenses and rentals on its proprietary and distributed software, recurring annual maintenance and support contracts, fee-based training (FactSage two-day courses at 88,000 JPY for general participants; ChemSheet training at 52,500 JPY; customized on-site training at 150,000-350,000 JPY per day), and a substantial commissioned analysis services practice (受託解析) covering structural, thermal-stress, vibration, fluid, wind-power, acoustic, heat-conduction, mesh-generation, post-processing, and GUI-development assignments. Free-tier distribution (ChemApp for Python Light) and a member portal support lead generation. Go-to-market is direct-sales-led from Tokyo and Osaka, complemented by an aggressive seminar and user-group program — the annual FactSage User Meeting has run for 24 years (since 2000), combining in-person and online delivery and bringing in developers from Germany, Finland, and Canada.

The customer base spans four primary segments: industrial CAE users in engineering and manufacturing, materials-science and process-engineering researchers (FactSage users in metallurgy, nuclear, cement, and waste treatment), civil-engineering and construction firms using ASTEA MACS, and medical/biomechanics researchers using MECHANICAL FINDER. Academic and national-laboratory customers are particularly visible (NIMS, JAEA, AIST, universities across Osaka, Tohoku, Chubu, Nagoya, Kansai, Kyushu) alongside industrial users such as JX Metals, Sumitomo, and Ube Industries. The company is privately held with no disclosed institutional ownership; the long-running JKA Social Action Programs grant appears as a peripheral funding signal. RCCM faces concentration, succession, and AI-displacement risks typical of founder-led Japanese niche-software firms.

Revenue model

1. Software Sales and Distribution: RCCM resells and distributes a wide range of third-party CAE and simulation software (Simcenter Nastran, ANSYS Fluent, Autodesk Moldflow, Solid Edge, Actran, etc.) as a distributor/dealer, alongside its own proprietary tools (ASTEA MACS, MECHANICAL FINDER). Revenue is generated through perpetual licenses, annual rentals, and license upgrades.
2. Maintenance and Support Contracts: Annual maintenance contracts for all distributed software products, providing updates, technical support, and hotline services.
3. Commissioned Analysis Services (受託解析): RCCM provides contracted analysis services including strength analysis, thermal stress analysis, vibration analysis, fluid analysis, wind power analysis, acoustic analysis, heat conduction analysis, mesh generation, post-processing, and GUI development.
4. Training and Seminar Services: Fee-based training courses for FactSage, ChemSheet, ChemApp and other products, held both at RCCM's training rooms and online. Course fees range from 55,000 to 88,000 JPY per person depending on course type and academic status.
5. FactSage Product Line (Licensing): As the exclusive Japanese distributor of FactSage and related products (ChemSheet, ChemApp, ChemApp for Python, KilnSimu) developed by GTT-Technologies and VTT, RCCM generates revenue through software licensing (permanent and rental), version upgrades, and database sales.
