You can now use the new Inertia Relief option to solve unconstrained models.

With the Inertia Relief option, a three-point constraint is placed on the model internally. It is using a 3–2–1 constraint with respect to the newly created UCS. The three-point constraints affect the displacement solution but not the stress solution.

If a model has constraints defined and you select the Inertia Relief option, then the defined constraints are ignored, and the study considers Inertia Relief instead.

This option is available only for structural studies.

Release: Creo Parametric 9.0.0.0

You can use this enhancement when you want to simulate a structure without constraints in Creo Ansys Simulation. The Inertia Relief option balances the external loading with inertial loads and accelerations within the structure.

This enhancement is useful for the models that can be considered floating freely in space, with loads applied.
