Starter Kit 1 - Introduction of MBD

RecurDyn Starter Kit Webinar - Multibody dynamics software

1. Definition of CAE

Computer-aided engineering (CAE) is the use of computer software to simulate performance in order to improve product designs or assist in the resolution of engineering problems for a wide range of industries.


2. CAE Softwares

4. MBD (Multi-Body Dynamics) 

Numerical simulation in which multibody systems are composed of various rigid or flexible bodies. Connections between the bodies can be modeled with joints, forces and contact.

The study of the dynamic behavior of an assembly of rigid or flexible bodies, usually including large translational/rotational displacement.

The calculation of loads (at joints, contacts and where forces are applied) that can be used for component-level structural analysis.

5. Process of MBD analysis




Starter Kit 2 - 7 reasons to use RecurDyn

1. System level analysis

  1. Real systems consist of several components and are operated by their interactions
  2. RecurDyn provides not just individual component analysis but the overall system level analysis
  3. Convenient UI and specialized solver for system level analysis

  • Using MFBD technology, RecurDyn can simulate a system containing rigid and Flexible Bodies including contact and large deformation and durability analysis are also supported within RecurDyn.


2. Load calculation for FEA

  • Boundary conditions and load conditions are required for FEA
  • It is not easy to get the boundary and load conditions for a dynamic system which involves dynamic motion and interactions between several parts
  • MBD results using System level analysis can be used as the boundary and load conditions of FEA

  • MBD for ANSYS is a Multi Body Dynamics software add-in developed by FunctionBay, which uses RecurDyn solver.
  • It can perform MBD simulation in the ANSYS environment and easily transfer the MBD results to ANSYS Structural analysis using a unique feature called ’Load Transfer’.
  • It is possible to perform MFBD simulation using RecurDyn without FEA software.


3. Specialized for MBD analysis

4. Not only Rigid body but also Flexible body

  1. 20~30 years ago, MBD focused on the rigid bodies. However, MBD can handle not only rigid bodies but also flexible bodies
  2. RecurDyn supports not only Reduced Flex (RFlex), but also Full Flex (FFlex)
  3. Mesh, Pre-process, simulation and even Post-process and Durability are supported in RecurDyn environment.

Starter Kit 3 - Applications of RecurDyn

1. Automotive

  • Analyze the dynamic behavior or calculate the load applied to each component by performing dynamic analyses on the full vehicle, suspension, engine, and clutch, considering various driving and operating conditions.
  • NVH of the Engine, lubrication mechanism of the transmission

Starter Kit 4 - Let's use RecurDyn

This is a self-study guide to learn how to use RecurDyn, which helps the students or the people who don't know how to use RecurDyn.

If you can create the bodies, joints or contacts and run simulation already, RecurDyn e-Learning or tutorial will be better than this guide.


First, please download the below files. 


Most of the pages include a video clips. So please watch the video first and then do it yourself.

(for some UIs, this guide introduce the UI of RecurDyn V8 and V9 both.)


For your information,this guide includes the following topics.


1. Pre-process

  • How to create Body, Joint, Force, Contact  
  • How to use View Control

2. Solve

  • The difference between Dynamic analysis and static analysis

3. Post-Process

  •  Animation
  • How to use Plot

4. Others

  • Request
  • Scope
  • Marker Trace & Force Display
  • Model setting
  • Animation during simulation
  • Relation Map
