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. | ||||||
