ANSYS Explicit Dynamics-Introduction to Workbench

ANSYS Workbench Overview

The Workbench environment supports two types of applications:

– Native applications (workspaces): Current native applications are Project Schematic, Engineering Data and Design Exploration.

Native applications are launched and run entirely in the Workbench window.

– Data Integrated Applications: current applications include Mechanical,Explicit Dynamics (Mechanical), Fluent, CFX, AUTODYN and others.

 

Starting Workbench

There are two methods of launching Workbench:

– From the Windows start menu:

The Workbench Environment

For most situations the Workbench GUI is divided into 2 primary sections (there are other optional sections we’ll see in a moment):

The 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.

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.

The 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:

–DesignModeler, Mechanical (formerly Simulation), Mechanical APDL (formerly ANSYS), ANSYS AUTODYN, ANSYS Fluent, ANSYS CFX, Etc . . .

Blocks of cells can be deleted by RMB menu selection.

In this example an Explicit Dynamics 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.

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.In the example below 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 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 each system block is given an alphabetic designation (A, B, C, etc)

By dropping the structural system at the “Solution” level we obtain a structural system that is coupled to the thermal solution.
