FunctionBay RecurDyn
FunctionBay RecurDyn is a sophisticated Civil Engineering Simulation (CAE) software solution focusing on Multi-Body Dynamics (MBD) analysis. Developed by FunctionBay (South Korea), this software utilizes a revolutionary mathematical solver that allows for the computation of mechanical systems containing both rigid bodies and flexible bodies within a single model.
The solution’s outstanding feature is its ability to handle extremely complex contact problems between thousands of moving parts at high speeds. Instead of simplifying the model to reduce accuracy, the software allows engineers to visually simulate mechanical systems under real-world operating conditions quickly and smoothly.

Features of FunctionBay RecurDyn
- Proprietary MFBD (Multi Flexible Body Dynamics) Technology
- This is the feature that has made FunctionBay famous on the global CAE map. MFBD technology allows the integration of components with plastic or elastic deformation (FE) properties into multi-body motion systems (MBD). Engineers can not only see how the machine mechanism moves, but also analyze the stress, fatigue, and deformation of each part during that movement without having to export data back and forth between different software.
- Ultra-fast mathematical solver and cutting-edge contact algorithm
- Handling contact forces between complex curved surfaces is always the most time-consuming area for computers. The software thoroughly solves this problem thanks to its advanced contact algorithm combined with a recursive matrix solver. The system is capable of calculating the trajectory and impact force of millions of contact points in real time with absolute stability and accuracy.
- Specialized Toolkits for Specific Industries
- The software provides expanded toolkits specifically designed to automate the modeling process for specific mechanical systems:
- Track LM/HM: Specifically designed for simulating tank tracks, excavators, and bulldozers on rough terrain.
- Gear/Belt/Chain: Automatically creates and simulates precise gear, belt, and chain drive systems.
- Valve/Piston: Optimized for analyzing camshaft, valve, and piston mechanisms in internal combustion engines.
- Co-simulation Capability
- This solution easily connects and synchronizes bidirectionally with control software such as MATLAB/Simulink for testing mechatronics systems. Additionally, it can be combined with particulate fluid simulation software (such as ParticleWorks) to calculate the interaction between fluid flow and moving mechanical mechanisms.
- FunctionBay RecurDyn is more than just a mechanical computation tool; it’s a comprehensive digital transformation solution that elevates the capabilities of modern simulation engineering. By pioneering the breaking of boundaries between multi-body system dynamics and finite element analysis, the software is the golden key that helps businesses optimize product performance, reduce development costs, and accelerate product delivery.
