Defining Remote Inertias

You can apply nonstructural mass and inertia components at one or more supports positioned away from the model geometry.

Support Selection
  1. From the Abstractions section of the action bar, click Remote Inertia .
  2. Optional: Enter a descriptive Name.
  3. Select geometry supports.

    Yo can apply remote mass and inertia to one or more points, edges, faces, or bodies. All selected supports must be the same type (homogeneous). For example, if you select an edge you can select more edges but not other support types.

  4. From the Point input mode options, select one of the following:
    OptionDescription
    Specify Chooses a point by editing the coordinates of the remote inertia feature triad on the model.
    Support Specifies the remote inertia location using a point on the model or a node-based group that contains a single node.
  5. If you chose Support in the previous step, select a Point on the model or a node-based group that contains a single node for the location of the remote inertia.

    Tip: You can right-click the Point field and select Create Support to create a new point or to create a proximity or a manual mesh group containing the required point.

  6. Enter the mass.
  7. Enter the inertia components in the 1-, 2-, and 3-directions (I11, I22, I33) and the products of inertia (I12, I13, I23).
  8. Choose an Axis system definition.

    • Global: Aligns the local feature triad with the global coordinate system.

    • Local: Aligns the local feature triad with a selected axis system in the model.

    • Specify: Orient the local feature triad directly by right-clicking the feature triad glyph on the model and selecting an orientation tool.

  9. Click OK.
