Understand Simulation Tools

Large and complex moving assemblies coupled with hundreds of articulated
moving parts can be simulated. Autodesk Inventor Simulation Simulation
provides:
Interactive, simultaneous, and associative visualization of 3D animations
with trajectories; velocity, acceleration, and force vectors; and deformable
springs.
Graphic generation tool for representing and post-processing the simulation
output data.

Simulation Assumptions

The dynamic simulation tools provided in Autodesk Inventor Simulation are
invaluable in the conception and development steps and in reducing the
number of prototypes. However, due to the hypothesis used in the simulation,
it provides only an approximation of the behavior seen in real-life mechanisms.

Interpret Simulation Results

Some computations can lead to a misinterpretation of the results or incomplete
models that cause unusual behavior. In some cases, a simulation can be
impossible to compute. To avoid these situations, be aware of the rules that
apply to:

Relative parameters

Continuity of laws
Coherent masses and inertia
Relative Parameters
Autodesk Inventor Simulation Simulation uses relative parameters. For example,
the position variables, velocity, and acceleration give a direct description of
the motion of a child part according to a parent part through the degree of
freedom (DOF) of the joint that links them. As a result, select the initial velocity
of a degree of freedom carefully.
