RecurDyn is a Professional Multi-Body Dynamics Simulation Software for CAE developed by FunctionBay, Inc.

RecurDyn is an innovative Multibody Flexible Body Dynamics (MFBD) based CAE software offering state-of-the-art Multibody Dynamics capabilities with a unique integrated powerful non-linear Finite Element Method. It returns more precise dynamic motion results including stress analysis in one single simulation step. It also features flexible body contacts and non-linear deformations.

The technology behind RecurDyn has superior calculation efficiency because it is based on recursive formulation. Because of this, RecurDyn gives the best performance in large-scale multibody problems (systems with many bodies), including mechanical systems that experience a lot of contact.

Along with the powerful solver, RecurDyn features a natural Windows-based User Interface which is intuitive and easy to use, as well as a custom application development environment which enables users to automate complicated and/or tedious tasks.
