    Introduction AssembliesIntroduction Assemblies

    The ANSYS Workbench represents more than a general purpose engineering tool. It provides a highly integrated engineering

    simulation platform. Supports multiple multi-physics engineering

    solutions. Provides bi-directional parametric associativity

    with most available CAD systems. This exercise is designed to introduce you to the

    import and use of Assemblies and Contact in the ANSYS Workbench

    PurposePurpose

    This tutorial is incremental in nature It is designed to introduce you to:

    The nature and design of the ANSYS Workbench User Interface

    The concepts of ANSYS Workbench Projects and Applets

    The integrated nature of ANSYS Workbench technology

    The power of the ANSYS Workbench in using applied parametric modeling and simulation techniques to provide quality engineering solutions

    Using AssembliesUsing Assemblies

    The methods taught in this tutorial apply equally well to both attached CAD and DesignModeler files.

    For the purposes of this tutorial we will be using the DesignModeler file produced in Exercise 4 of this tutorial.

    When using attached CAD systems auto-contact generation works with parts imported from from your CAD models.

    Using Contact RegionsUsing Contact Regions

    Contact regions generated by auto-contact in the ANSYS Workbench allow you to define and refine the relations between various parts in an assembly.

    Contact regions can also be used to define joint relationships for Multi-body dynamics.

    Remember: When importing or connecting to CAD

    systems you can import simple parts or full assemblies

    Contact regions will be created in Simulation for all appropriate regions

    Care should be taken to ensure the proper definition and interaction of these regions in the model
