Selecting occurrences for studies

When creating a new study of an assembly model with a Mixed or Tetrahedral mesh type, the Simulation tab→Geometry group→Define command runs automatically. You are prompted to select one or more occurrences. You can use Ctrl+click to select individual parts, click+drag to fence-select a group of parts, and use the following options on the command bar to select parts to include in the study.

Selecting all occurrences at once

Choose the Select All button on the command bar to automatically add all visible (shown) geometry in the model to the study. This includes both active and inactive parts in the assembly, but not suppressed parts. When an inactive occurrence is added, its status is changed to active.

Note:

To include a part that is marked as suppressed (), you must first unsuppress it using the Unsuppress shortcut command. Then you can select the Define command and use the Select All button.

Selecting individual occurrences for a study

For occurrences that are displayed but are inactive, click the parts and subassemblies in the graphics window to activate them automatically, or select the Home tab→Select group→Activate command .

Adding occurrences to a study

You can add parts and subassemblies to the geometry selected for the study using the Define command on the shortcut menu of the Simulation pane→Geometry node.

For example, you can select a subassembly in PathFinder, and all occurrences of the subassembly are added to the selection set for the study.

You also can change the geometry that is included in an existing study. To learn how to do this, see Add or remove study geometry.

Selecting simplified geometry

• You can make a simplified part available for a study in an assembly model when you select the Use Simplified Part command on the part shortcut menu on the PathFinder tab.

• In the Simulation environment, use the Define command to select a simplified body in the graphics window. You also can select the mid-surface, faces, edges, or vertices from a simplified body.

  Note:

  • To simplify parts for use in an assembly, open the part for editing and use the Tools tab→Modify group→Simplify command. For more information, see Simplifying parts.

  • Whatever state the geometry is in when you select it is the state that is added to the study.

When you choose a Beam mesh type to analyze a frame model, you are prompted to select one or more frames.

Selecting frames

• You can select multiple frame features by dragging a box around them, or you can select them individually in the graphics window or in PathFinder.

• Each frame feature can have multiple beams with varying cross sections and different materials.

• As for assembly occurrences, you can use the Define command to add new frames to a study.
