MBD for ANSYS (Multi-Body Dynamics for ANSYS) is an add-on module for ANSYS that is used to simulate the transient behavior of a mechanical assembly in motion and is developed by FunctionBay.

4 ADVANTAGES

1. Consistent user interface with ANSYS Workbench

Provides an easy and intuitive modeling experience for Multi-Body Dynamics.

2.Fast and Robust Solver
      Developed by the professionals of Multi-Body Dynamic
      Fast simulation using rigid bodies (transient analysis)
      High performance contact algorithm
      Complicated multi-body system & Nonlinear contact problems

3. Automated and Intelligent LoadTransfer

      To generate accurate loads, physical tests, empirical values, or just outright guesses are often used.
      But this is expensive, time consuming, and often inaccurate.
      Transient FEA can calculate the loads. But difficulty of use, slow calculation, and poor convergence are barriers to using transient FEA.
      Automated and Intelligent Load Transfer MBD for ANSYS can generate accurate loads and provides automated and intelligent loadtransfer process.
      MBD simulation outputs are transferred as loads on a FEA model automatically!

4. Scalability to various Multi-Body Dynamics applications

      MBD for ANSYS can be used to understand the dynamic behavior of basic mechanical assemblies and generate loads for structural analysis
      In addition, there are many applications of Multi-Body Dynamics such as complex assemblies with vibration problems; mechatronic systems that couple mechanical assemblies, sensors and controllers; and complex multi-body systems with chains, belts, bearings, gears and track assemblies.
      Some systems require the co-simulation of mechanical assemblies and fluids using particle dynamics. MBD for ANSYS lets you export your model to the RecurDyn standalone, high-end MBD software, which is able so simulate such complex systems.
