10B. ANSYS Workbench Overview
- What is ANSYS Workbench?
- ANSYS Workbench is a new-generation solution from
ANSYS that provides powerful methods for
interacting with the ANSYS solver functionality.
This environment provides a unique integration
with CAD systems, and your design process,
enabling the best CAE results. - ANSYS Workbench is comprised of five modules
- Simulation for performing structural and thermal
analyses using the ANSYS solver - CFX-Mesh for generating a CFX-Pre mesh for the
CFX-5 solver - DesignModeler for creating and modifying CAD
geometry to prepare the solid model for use in
Simulation or CFX-Mesh - DesignXplorer and DesignXplorer VT for
investigating the effect of variations input to
the response of the system - FE Modeler for translating a Nastran mesh for use
in ANSYS
11 ANSYS Workbench Overview
12 Simulation Overview
- Analysis types available in Simulation
- Linear Stress
- Determines deflections, stresses, factors of
safety, etc. based on standard strength of
materials concepts under static loading - Modal
- Determines natural frequencies of a system (free
vibration), including the effects of loading on
a pre-stressed structure. - Heat Transfer
- Steady-state and transient
- thermal analyses to solve for
- temperature field and heatflux.
Temperature-dependent conductivity and
convection allowed. Thermal-stress
analysissupported as well.
The list here reflects analysis capabilities
possible within the Simulation GUI. Note,
however, that the ANSYS license used dictates
what functionality is available to the user.
13 Simulation Overview
- Analysis types supported by Simulation (contd)
- Harmonic
- Determines structural response of system under
sinusoidal excitation as a function of frequency. - Linear Buckling
- Determines failure load or safety factor for
buckling and its buckling mode shapes. - Shape Optimization
- Indicates areas of possible volume reduction
based on load paths through the part using
Topological Optimization technology. - Nonlinear Structural
- Calculates deflections and stresses of system
under static loading, accounting for large
deflection effects, plasticity, and contact
nonlinearities.
The list here reflects analysis capabilities
possible within the Simulation GUI. Note,
however, that the ANSYS license used dictates
what functionality is available to the user.
14 Simulation Overview
- Although the Simulation GUI will be discussed in
detail in Chapters 2 3, it is useful to note
that it is Tree-Driven
Depending on what is highlighted on the Outline
Tree, the available options in the Context
Toolbar and Details View will change. The
Graphics Window will also update to reflect the
part of the branch selected. The Tree represents
the different aspects of the simulation. All
Workbench modules are Tree-Driven, so navigation
through the GUI is done through selecting
different branches of the Tree.
15 Simulation Overview
- The user can also access regular ANSYS
functionality not otherwise directly accessible
from within Simulation - Command objects allow users to stay in the
Simulation environment but access advanced
features via ANSYS APDL. The information, stored
in a branch, can be parameterized and is reused
for each analysis. - The mesh and loads can also be transferred to
regular ANSYS easily for further modeling,
useful for userscomfortable in the regular
ANSYSenvironment - Both of the above topics are addressed inthe
Simulation Advanced Training Notes

20C. Starting Simulation
- There are two methods of launching Simulation
- Directly from CAD system
- Launch Simulation from supported CAD systems
under ANSYS 9.0 gt Simulation - From within ANSYS Workbench
- Launch Workbench in Windows via Start Menu gt
Programs gt ANSYS 9.0 gt ANSYS Workbench
21 Option 1 Directly from CAD
- If Simulation is launched directly from a
supported CAD system, the active part/assembly
will be brought into Simulation automatically
upon invoking Simulation from the ANSYS 9.0
pull-down menu, as illustrated below
22 Option 2 From Workbench
- Otherwise, a user may launch Workbench first
- From the main Start page, select Simulation
icon to bring up a blank Simulation session - From the Context toolbar, select the active
part/assembly under the Geometry branch to
bring in the CAD geometry
23 Launching Simulation
- For supported CAD systems, either method shown on
the previous slides may be used to start
Simulation. - For neutral files (e.g., CATIA, IGES, SAT (ACIS),
or Parasolid), the user must implement Option 2
and launch Workbench first. After a blank
Simulation database is opened, the static file
can be referenced via the Context Toolbar, under
Geometry gt From File
24D. Workbench Projects
- When ANSYS Workbench is launched, a Start page
will be displayed, similar to the one shown below
25 Options Page
- Before entering Simulation, the current and
default licenses may be chosen through the
Options button - This is useful for organizations with multiple
types of ANSYS licenses (e.g., DesignSpace,
Structural, Mechanical, etc.) - Preferences for all Workbench modules can also be
controlled through this dialog box
26 Workbench Databases
- There are various types of files used by
Workbench, each differentiated by the file
extension - .wbdb Workbench Project database, which keeps
track of all of the different types of Workbench
databases in a Project - .dsdb Simulation database, which has all the
information necessary to perform a structural or
thermal analysis in Simulation - .agdb DesignModeler database, containing
geometry data for use with Simulation or CFX-Mesh - .dxdb DesignXplorer/DesignXplorer VT database,
which investigate relationships between input and
output parameters - .cmdb CFX-Mesh database, containing a mesh
prepared for import to CFX-Pre and to be solved
with CFX-5 - .fedb FE Modeler database, which has mesh
information from a Nastran or Simulation model,
used to convert to ANSYS
27 Workbench and Simulation
- The Workbench database is simply a directory of
a Project. A Project can be thought of as a
collection of different CAD or Workbench files,
which are associated together. - Whenever a Simulation database (.dsdb) is
created, there will be an associated Workbench
database (.wbdb) generated as well. - Saving the Workbench database is not required,
but it is helpful in keeping track of various
analyses, especially if multiple geometries are
analyzed or if further analysis is performed with
DesignXplorer.
28 Workbench and Simulation
- If the Workbench Project tab is selected, the
various Workbench databases and CAD geometries
will be listed
29DesignModeler Overview
- DesignModeler (DM) is a component of ANSYS
Workbench. - A CAD-like parametric modeler with analysis
modeling goals - 2D, 3D ,line and surface modeling capability
- Performs unique geometry modification
capabilities for simulation - Feature Simplification
- Spot Welds
- Split Surfaces
- Surface Model Extraction
- Planar Body Extraction
- Beam Modeling
- Enclosure Operation
30. . . DesignModeler Overview
- Much of the DM GUI is functionally the same as
that of Simulation. - A complete DesignModeler Training course is
available.
31 Navigating Between Modules
- The topmost tabs allow users to navigate between
opened Workbench modules
32 Exiting Workbench
- When exiting Workbench, the user will be prompted
to save any files that have changed since the
last save
