RecurDyn e-Learning Online Study Program
In September, we introduced you to the new RecurDyn e-Learning platform which provides users a resource to learn how to use RecurDyn through self-study at home, work or school.
Let’s take a closer look at what this valuable resource can do for you…
PS. Not yet a RecurDyn user but would like to learn and follow along with us? Please contact us for a free 30-day trial of RecurDyn.
Step 1: The Starter Kit
The Starter Kit is an introduction to Multi-body Dynamics. It defines MBD, includes types of software used, how MBD is used to improve product development and the process of analysis.
Click the button below to get started with your e-Learning experience.
Step 2: e-Learning Start
e-Learning Start is a self-guided course through 6 different model building exercises that teach the basics of the modeling process using RecurDyn.
It includes all learning materials to walk you through each module creation step-by-step.
Click the button below to get started on the next level of learning RecurDyn and MBD modeling.
Step 3: e-Learning Dynamics
e-Learning Dynamics continues on where e-Learning Start left off with more lessons to help the user expand upon the basics.
Dynamics of Particles has 10 lessons to help you better understand and use RecurDyn when building models with particles.
Dynamics of Rigid Bodies has 20 lessons to help you with using rigid bodies in your models.
All lessons include RecurDyn videos by FunctionBay and/or downloadable sections of the Engineering Mechanics: Dynamics textbook by James L. Meriam, L.G. Kraige and J.N. Bolton.
Click the button below to expand your skills in particles and rigid bodies modeling.
Step 4: RecurDyn Tutorials
RecurDyn Tutorials goes into detailed explanations with videos and downloadable lessons for even more experience with modeling and will give users a better understanding of the RecurDyn framework.
Each topic has from 1 to 9 different scenarios to learn from. The areas of interest are:
● Professional
● MFBD
● CoLink
● AutoDesign
● ProcessNet
● Toolkits
● eTemplate
● Communicator
● MBD for ANSYS
Click the button below to expand your knowledge/skills with RecurDyn and become a more advanced RecurDyn user.
Step 5: Basic MBD Models
Now that you have a strong background in modeling, MBD and RecurDyn, it’s time to take what you have learned and use it to create basic MBD models.
These models consist of motion objects such as Body, Joint, Force and Contact. Modeling descriptions and datasheets in the tutorials are based on MBD for ANSYS, however, users can create these basic MBD models using either RecurDyn or MBD for ANSYS. Model files for both software are provided within the lessons along with details and the corresponding CAD file.
Don’t have RecurDyn or MBD for ANSYS? Click here to contact MotionPort to receive a free 30-day trial license for either RecurDyn or MBD for ANSYS.
If you are an ANSYS Workbench user and have the Mechanical-related package and Design Modeler, you can download MBD for ANSYS Lite and use it for these Basic MBD Models (free 30-day trial).
Let’s get started!
Click the buttons below to create one or all of the sample models.
Basic MBD Model – Water Pump
Description: With this simple Water Pump model, you can learn how the contact behavior of the pump piston corresponds to the movement of the lever.
Main Results :
● Angular Displacement of the ‘Lever_long’ body
● Position of ‘Pump_action’ body in Y axis
Basic MBD Model – Bending Machine
Description: The dynamic behavior of the Bending Machine
consists of several bodies, joints and contacts which can be explored.
Main Results :
● Driving Torque of Gear
● Contact Force (Punch to Die)
Basic MBD Model – Planet Gear
Description: This is a simple Planet Gear model. The vibration and the rotational behavior by contacts among gears can be investigated.
Main Results :
● Driving Torque of ‘PlanetGearCarrier’
What’s New in V9R2: Multi Flexible Body Dynamics
V9R2 has improvements in multi flexible body dynamics in areas such as:
● Auto mesh
● Remesh
● Quality Checks
● Mesh Healing
Improvements have also been made to MFBD models with FFlex and RFlex bodies. These improvements in speed to open model files, simulation speed and performance in various post-processing tasks.

User Tip:
How can I apply a boundary condition to a RFlex body?
A user can apply a boundary condition to an FFlex Body directly in the FFlex Body Edit mode.
But a boundary condition for an RFlex body cannot be applied…
