About Inertia Relief

Inertia relief is a simulation method used to perform static analysis on free or partially constrained bodies. Inertia-based loads are applied to balance external forces acting on the bodies.

Applying Inertia Relief

In inertia relief, the mass of the body is used to resist the applied loads, and it is assumed that the body is in a state of static equilibrium without being fully constrained. An example of using an inertia relief load is modeling a rocket undergoing constant or slowly varying acceleration during lift-off with a static analysis procedure.

Inertia relief is a step-dependent action. Only one inertia relief load can be defined in a scenario, and it is applied to all degrees of freedom.
