SS-T: 4140 Global-local Analysis

Create global-local analysis.

Prerequisites
Some features used in this tutorial are only available in the SimSolid Advanced version. Switch to Advanced to complete this tutorial.
Purpose
SimSolid performs meshless structural analysis that works on full featured parts and assemblies, is tolerant of geometric imperfections, and runs in seconds to minutes. In this tutorial, you will do the following:
  • Learn how to create a global-local analysis in SimSolid.
Model Description
The following model file is needed for this tutorial:
  • Wing_GlobalLocal.ssp
Figure 1.


The model (.ssp) file has the following specifications:
  • Material is set to Aluminum and Steel for wing and fixture assemblies.
  • Imported rivets.
  • Regular connections with 3mm gap and penetration tolerance.
  • Structural analysis with boundary conditions applied on the fixture and skin.

Open Project

  1. Start a new SimSolid session.
  2. On the main window toolbar, click Open Project .
  3. In the Open project file dialog, choose Wing_GlobalLocal.ssp
  4. Click OK.

Review Model

In the Project Tree and modeling window, review the assembly, connections, and the analysis.
Figure 2.

Create Local Analysis

Create a local study on the fixture.

  1. In the Bookmark Browser, click Bookmark 1 to isolate the fixture assembly.
  2. In the Project Tree, select Global Study, BASELINE to open the Design Study workbench.
  3. Click Create local study .
  4. Select parts as shown in Figure 3.
    Figure 3.


  5. Under Copy Analysis, verify Structural 1 is selected.
    This section of the dialog lists all Structural Linear and Structural Non-linear analyses present in the current design study. All listed analyses are selected by default.
  6. Click OK.
    The linked design study inherits all the properties, connections and boundary conditions for the selected part from the global study. Reaction forces from the connected parts are also mapped to the local linked analysis.
    Figure 4.
    Note:
    • Any changes to material, part type, connections, analysis set up, boundary conditions made to the global analysis are reflected in the local analysis.
    • Analysis in global study should have a valid result to run the linked local analysis.

Run Analysis

  1. On the Project Tree, open the Analysis Workbench.
  2. Click Solve.
SimSolid runs the analyses in Design study 1. When finished, a Results branch for each analysis appears in the Project Tree.

Review Results

  1. On the Analysis Workbench toolbar, click Result plot > Displacement > Displacement magnitude.
  2. Click Deformed shape .
