The multibody modeling process contains a set of well-defined, sequential

steps. Before you begin, define the intent of the model. Then, select a

modeling approach and define the model requirements.

SimMechanics supports two modeling approaches:

• Manually build model — most common modeling approach. The following

sections outline the manual approach.

• Automatically generate model from CAD assembly — for users wishing to

simulate a CAD assembly in a physical modeling environment. Approach

requires access to supported CAD software and assembly files. See “CAD

Translation”.

Model Rigid Bodies

Rigid bodies are the building blocks of a multibody system. Before you can

connect rigid bodies with joints and constraints, you must model the rigid

bodies. You can create two types of rigid bodies:

• Simple — Use a single Solid block to model the rigid bo dy. Simple rigid

bodies are quicker to m o d e l. U s e simple rigid bodies to quickly produce

proof-of-concept models, before you create more detailed rigid body

subsystems.

A simple cylinder is a simple rigid body.
