    Training ManualThe Workbench Environment

    For most situations the Workbench GUI is divided into 2 primary

    sections (there are other optional sections well see in a moment):

    The Toolbox The Project Schematic

    Training ManualThe Toolbox

    The toolbox contains 4 subgroups:

    Analysis systems:

    Predefined templates that can be

    placed in the schematic.

    Component systems:

    Various applications that can be

    accessed to build, or expand,

    analysis systems.

    Custom Systems:

    Predefined analysis systems for

    coupled applications (FSI, thermal-

    stress, etc.). Users can also create

    their own predefined systems.

    Design Exploration:

    Parametric management and

    optimization tools.

    Training ManualThe Toolbox

    The systems and components

    displayed in the toolbox will

    depend on the installed

    products.

    Using the check boxes in the

    View All / Customize

    window, the items displayed

    in the toolbox can be toggled

    on or off.

    The toolbox customization

    window is normally left closed

    when not in use.

    Training ManualThe Project Schematic

    The Workbench project schematic is a graphical representation of the

    workflow defining a system or group of systems.

    The workflow in the project schematic is always left to right.

    There are currently several applications which are native to

    Workbench, meaning they run entirely in the Workbench window:

    Project Schematic, Engineering Data and Design Exploration

    Non-native applications (called data-integrated) run in their own

    window:

    Mechanical (formerly Simulation), Mechanical APDL (formerly ANSYS),

    ANSYS Fluent, ANSYS CFX, Etc . . .

    Blocks of cells can be deleted by RMB menu selection.

    Training ManualThe Project Schematic

    In this example a Static Structural analysis type is selected for the

    project schematic.

    From the toolbox the selection can be dragged and dropped onto

    the schematic or simply double clicked.

    Training ManualThe Project Schematic

    In the example shown a

    structural system is dragged and

    dropped onto a thermal system

    at the Model cell (A4).

    Before completing the operation

    notice there are a number of

    optional drop locations that

    will provide various types of

    linkage between systems

    (continued next page).

    By dropping applications and/or analyses into various locations in

    the schematic, an overall analysis project is defined.

    Connectors indicate the level of collaboration between systems.

    Training ManualThe Project Schematic

    By completing the operation from the previous page, notice the

    linkage here is only at the Model level and above.

    In this case there would be no thermal/structural coupling.

    Notice too each system block is given an alphabetic designation (A,

    B, C, etc.).

    Training ManualThe Project Schematic

    By dropping the structural system at the Solution level we obtain a

    structural system that is coupled to the thermal solution.

    Notice, the candidate

    drop location

    indicates data will be

    shared from fields A2

    to A4, and

    transferred from A6.

    A schematic can also be constructed by RMB and choosing to

    Transfer Data To New or Transfer Data From New.

    In using the RMB transfer feature all transfer possibilities (upstream

    and downstream) are displayed.

    These selections will vary depending on which cell in a particular

    system you highlight.

    Identifying cell states:

    Unfulfilled: missing upstream data.

    Attention required: may need to correct this or upstream cells.

    Refresh required: upstream data has changed. Need to refresh cell. An update

    will also refresh the cell and regenerate any output data (e.g. mesh, results).

    Update required: the data has changed and the output of the cell must be

    regenerated.

    Up to date.

    Input changes pending: cell is locally up to date but may change when the next

    update is performed due to upstream changes.

    Interrupted: solver was manually stopped before it finished. Can use Resume

    or Update to continue to solving.

    Pending: a batch process is in progress

    Training ManualWorkbench File Management

    Workbench creates a project file and a series of subdirectories to

    manage all associated files.

    Users should allow Workbench to manage the directories.

    Please do NOT manually modify the content or structure of the project

    directories.

    When a project is saved a project file is created (.wbpj), using the

    user specified file name (e.g. MyFile.wbpj).

    A project directory will be created using the project name. In the

    above example the directory would be MyFile_files.

    A number of subdirectories will be created in the project directory.

    Now launch Workbench on your training machine

    Start > All Programs > ANSYS 12.0 > ANSYS Workbench

    Expand the Component Systems toolbox and add a CFX system to

    the Project Schematic

    Drag a second CFX system onto the Project Schematic, dropping it

    onto the Solution cell of the first

    The first Solution is used as the starting point for the second Solution,

    e.g. a steady-state run followed by a transient run

    Right-click on the Setup cell in the first system and select Edit

    This will open CFX-Pre

    You can leave CFX-Pre open for now
