In this tutorial, you will learn how to simulate a model which has a flexible body.

You will start with an existing model which has all rigid bodies, and replace one of them with a RecurDyn RFlex body. RecurDyn RFlex uses a modal approach to represent flexible bodies, by using the superposition of the body’s natural modal shapes and constraint modes at the attachment points.

This approach is ideal when the flexible body has only fixed connection points to other bodies. If it has sliding or rolling contact, RecurDyn FFlex should be used, which takes a nodal (or mesh-based) approach to represent the body.
