What Function Bay does
FunctionBay, Inc. is a privately held Korean CAE (Computer-Aided Engineering) software developer founded in 2000 and headquartered in Seongnam's Pangyo Seven Venture Valley. The company builds and commercializes RecurDyn, a multi-body dynamics (MBD) simulation platform distinguished by its Multi-Flexible Body Dynamics (MFBD) technology, which integrates rigid body dynamics with non-linear finite element analysis in a single solver. The product architecture follows a platform-plus-modules model: RecurDyn/Professional serves as the required base, with optional toolkits spanning flexible body analysis (FFlex, RFlex), durability and acoustics post-processing, linear vibration, controls co-simulation (CoLink, Control via FMI), design optimization (AutoDesign), and industry-specific kits for machinery (Gear, Chain, Belt), engine components (Valve, Piston, Crank, EHD), tracked vehicles (TrackHM, TrackLM), and media transport (MTT2D, MTT3D, R2R2D). The company also distributes Particleworks, a particle-based CFD software from Prometech, integrated with RecurDyn for fluid-structure interaction.
FunctionBay sells through wholly-owned subsidiaries in South Korea (HQ), Japan, China, Germany, and Italy, supplemented by dealer networks across Taiwan, India, Australia, Switzerland, France, Singapore and the USA. The customer base spans automotive, construction machinery, aerospace, defense, office equipment/printer, robotics, and heavy industry, with named enterprise users including Samsung Electronics, Hanwha Corporation, Hitachi Construction Machinery, Sany Heavy Industry, and Woojin Plaimm. Revenue is generated through software licensing (base RecurDyn/Professional plus add-on toolkits) on a recurring model, with pricing not publicly disclosed. The company has accumulated multiple registered patents on MBD/MFBD methods, holds ISO 9001 certification, has been designated a Korean Advanced Technology Center, and received repeated Korean government recognition including the IR52 Jang Young-Shil Award (2004) and Korean World-class Product Awards (2006, 2012).

Product offeringCore offering
FunctionBay develops and sells RecurDyn, an interdisciplinary Computer-Aided Engineering (CAE) software platform for Multi-Body Dynamics (MBD) and Multi-Flexible Body Dynamics (MFBD) simulation that combines rigid-body dynamics with non-linear finite element analysis, contact modeling, control co-simulation, fatigue/durability analysis, and design optimization. The product is sold as a base RecurDyn/Professional module plus add-on industry toolkits (gear, chain, belt, engine components, tracks, media transport, EHD, tire, etc.), and the company also distributes Particleworks particle-based CFD software for fluid-structure interaction coupling with RecurDyn.
Product overview
Function Bay provides a comprehensive CAE software portfolio centered around RecurDyn, an interdisciplinary Multi-Body Dynamics (MBD) simulation platform that combines rigid body dynamics with Multi-Flexible Body Dynamics (MFBD) technology. The product suite operates on a platform-plus-modules architecture where RecurDyn/Professional serves as the required base component, with specialized toolkits extending functionality across multiple engineering domains. Key modules include FFlex and RFlex for flexible body analysis, Durability and Acoustics for post-analysis, Linear for vibration analysis, CoLink and Control for mechatronics simulation, and AutoDesign for optimization. Industry-specific toolkits cover machinery (Gear, Chain, Belt), engine components (Valve, Piston, Crank), track systems (TrackHM, TrackLM), media transport (MTT2D, MTT3D, R2R2D), and specialized analysis (EHD lubrication). The portfolio also includes Particleworks, a particle-based CFD software from Prometech, which integrates with RecurDyn through dedicated co-simulation interfaces for Fluid Structure Interaction (FSI) analysis.
