Point inertias can represent both the mass and inertia of components that do not change the structure of the current model. For example, when you analyze a part that is rigidly connected to other parts, you can define and position the mass and inertia components of those parts to simulate their impact accurately without adding the parts to the assembly. Point inertias are applied at one or more points within the existing model. Alternatively, you can define remote inertias to account for mass or inertia connected at a remote location. For more information, see Remote Inertias. Using point inertia simplifies the simulation model. Well-defined point inertias require less setup and computational expense than a complete model, while still delivering results that account for the parts that are not included. |
