TRAINING PROGRAM

This course will allow you to discover how to perform finite element analysis of a part or existing assembly. You will explore the possibilities of adding virtual parts to a model. 

You will also look in detail at how to create connections between assembly components, how to assign suitable connection properties and how to create an analysis assembly using existing meshed parts.

Advanced pre-processing tools:

• Rigid bodies, flexible bodies (virtual parts)

• Rigid/flexible bodies + springs

• Rigid/flexible bodies + contact elements

• Advanced fastenings on virtual parts
