FunctionBay RecurDyn V9R4 SP1 Update

The FunctionBay development team is pleased to announce the availability of RecurDyn V9R4 SP1. The V9R4 release allows to better design with improved modeling conveniences and MFBD functions. It is now possible to consider the thermal stress and thermal expansion due to temperature changes within a flexible body in RecurDyn and to easily create a gear with flexible webs.


RecurDyn is an interdisciplinary, computer-aided engineering (CAE) software package whose primary function is the simulation of Multi-Body Dynamics (MBD). RecurDyn simulates both rigid and flexible body dynamics by combining traditional rigid MBD with cutting-edge finite element technology for modeling flexible bodies. In addition, RecurDyn also includes a tightly-integrated controller design tool, design optimization, particle dynamics for granular materials, and durability and fatigue analysis. RecurDyn also supports co-simulation with various other computer-aided engineering software tools. RecurDyn includes a seamless co-simulation environment for coupled simulations with computational fluid dynamics solver, Particleworks from Prometech, allowing for detailed analysis of the interaction of fluids and multi-body systems.
