- Assembly
  Learn how to create, open, import and save models.
  - Assembly Browser
    The Assembly Browser is an object-oriented modeling environment where the fundamental entity is the module entity.
  - Module Symmetry
    Allows symmetric creation of LP Modules, Connections and dynamic LCS.
  - Module Reparenting
    Module Reparenting allows you to change the assembly hierarchy by cutting or pasting the modules.
  - Module Roll-Up/Roll-Down
    Set parent modules with CMS SE representation in H3D format to be used for analysis in lieu of child module representations when rolled up, or use the child representations when rolled down.
  - Module Subsystem
    Select and define a set of modules as the subsystem used for analysis.
  - Edit Module
    To manage any of the modules shown in the Assembly Browser, right-click a module and select Edit Representations. This opens the Edit Module tab, and the Representation sub-tab is shown.
  - Batch Create Assembly
    Create a complete vehicle assembly using external .csv files for assembly, tagpoints, connections, isolator, network diagram, symmetry and analysis.
  - Batch Create Module
    Use Batch Create Module to create assembly hierarchy and assign ID ranges to the modules from external .csv files.
  - Tagpoint Mapping Tool
    Use the Tagpoint Mapping Tool for automated mapping/creation of tagpoints and connections between data from different sources.
  - Connection Creation
    Connections can be created using the Create Connection-Interactive and Create Connection-Automatic tools.
  - Connection Browser
    Once the connections have been created, use the Connector Browser to review the connections.
  - Connection Manager
    Connections can be managed by right-clicking a connector in the Connector Browser and selecting Edit Connection.
  - Connection Mapping Tool
    Use the Connection Mapping tool for connection, property and hardpoint mapping.
  - Import Optimized Data
    Use the Optimization tool to automate mapping and update NVH connection parameters and modal parameters with optimized values from OptiStruct generated deterministic optimization output.
  - Connection Realization
    Use the Connection Realization tool for realization of selected connections based on the specified Tolerance, Property state and State rule.
  - LCS Manager
    Manage local coordinate systems (LCS) created in the Assembly framework.
  - Network View
    The network view is a block diagram view emphasizing inter-connectivity of the assembly.
- Analysis
  Set up the simulation model, materials, domains and boundaries.
- NVH Tools
- Prepare Module
  Create, organize and manage the CAE parts.
- Post-Processing and Diagnostics
  Define radiation conditions and create emissivity models.
High Frequency NVH
High frequency NVH is an implementation of Statistical Energy Analysis (SEA), and is used to predict and analyze the vibration and acoustic response of complex dynamic systems.
Squeak and Rattle
Create and evaluate evaluation lines and optimize interfaces to eliminate squeak and rattle issues.

Batch Create Module

Use Batch Create Module to create assembly hierarchy and assign ID ranges to the modules from external .csv files.

It is also possible to assign ID ranges manually. It shows the detailed summary of module ID ranges in terms of assignment, validity and conflicts.

Right-click a module in the Assembly Browser and select Batch Create Module to open the dialog.

Assembly Hierarchy Creation and ID Assignment from an External CSV File

Click Import to open the Import modules and id ranges dialog.
Load a .csv file that has assembly hierarchy and ID assignment definition.
Select the modules and click OK to create modules in hierarchy and assign ID ranges.

All of the modules and corresponding ID ranges are populated on the left hand side. Use the Assign arrow to create the modules and assign ID ranges. You can also unassign the ID range by clicking the Unassign arrow.

Figure 1.

Assignment, Validity and Conflicts Status of Module ID Ranges

The detailed summary of module ID ranges in terms of assignment, validity and conflicts is shown in the ID Manager with color coding. ID ranges for the modules can be exported in external .csv files using the Export button. The assigned ID ranges for modules can be modified/changed using the Edit icon. It is possible to visualize all modules in an assembly or only child modules with representation files. There are also options to view Open and Open+ ranges.
