Inertia can be defined for a part in the Property module or for an assembly in the Interaction module. You can specify the following types:
Point mass/inertia. You can define lumped mass and rotary inertia at a point on a part or on an assembly. In an ABAQUS/Standard analysis you can also define mass and inertia proportional damping and composite damping. For more information, see the following:
Nonstructural mass. You can define nonstructural mass for a region on a part or on an assembly. For more information, see “Nonstructural mass definition,” Section 2.6.1 of the ABAQUS Analysis User's Manual.
Heat capacitance. You can define concentrated heat capacitance at a point on a part or on an assembly. For more information, see “Point capacitance,” Section 16.4.1 of the ABAQUS Analysis User's Manual.
InertiaCreate: type from the main menu bar in the Property module or the Interaction module to define inertia. Select Edit from the same menu to make changes to an existing definition.Inertia definitions appear in the Model Tree in the Engineering Features container under the part (if created in the Property module) or under the assembly (if created in the Interaction module).
When you apply inertia to regions of the model, you can choose to display symbols in the viewport that indicate where you have applied the inertia. If you apply inertia to native geometry, symbols appear at the vertices. If you apply inertia to an orphan mesh, symbols appear at the nodes. For information about graphical symbol types, see “Symbols used to represent special engineering features,” Section B.3. For information about controlling the visibility of these symbols, see “Controlling the display of attributes,” Section 50.11.
