This document provides an overview of ANSYS Workbench software for structural and thermal analysis. It describes the user interface, types of analysis available including linear static, modal, heat transfer and buckling. It outlines the steps to set up a static structural analysis including importing geometry, applying materials, meshing, boundary conditions and solving. License types are also summarized. The goal is to teach the basics of using simulation capabilities in ANSYS Workbench.

2. Introduction
• Welcome to the ANSYS Workbench introductory training
course!
• This training course covers the basics of using Simulation
in performing structural and thermal analyses.
• There are some differences in ANSYS APDL and ANSYS
Workbench.
• User interface of Workbench is much easier than APDL.

3. Course Objectives
• To teach the basics of using Simulation in the following
areas:
• General understanding of the user interface, as related
to geometry--------
• import, meshing, application of loads and supports,
and post-processing.
• Procedure for performing FEA simulations, including
linear static, modal, and Heat analyses.

4. About ANSYS
ANSYS, Inc.
• Developer of ANSYS family of products
• Global Headquarters in Canonsburg, PA - USA (south of
Pittsburgh)
• Development and sales offices in U.S. and around the
world
• Publicly traded on NASDAQ stock exchange under
“ANSS”

5. About ANSYS Workbench
• 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.

7. Analysis types in Workbench
• Analysis types available in Simulation:†
• Linear Stress:
• Determines deflections, stresses, factors of safety,
etc. based on standard strength of materials
concepts under static loading

8. • Modal:
• Determines natural frequencies of a system (free
vibration), including the effects of loading on a pre-
stressed structure.

9. • Heat Transfer:
• Steady-state thermal analyses to solve for
temperature field and heat flux. Temperature-
dependent conductivity and convection allowed.
Thermal-stress analysis supported as well.

10. • Harmonic:
• Determines structural response of system under
sinusoidal excitation as a function of frequency.

11. • 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.

12. Types of licenses
• Types of licenses available for Simulation:
• ANSYS DesignSpace Entra
• All DesignSpace capabilities but for parts only.
• ANSYS DesignSpace
• Structural capabilities are linear static, modal, and buckling analyses
of assemblies. Thermal and shape optimization included.
• ANSYS Professional
• Linear structural (including harmonic) and thermal analyses
• ANSYS Structural
• All structural capabilities, including linear and nonlinear
• ANSYS Mechanical (including ANSYS Multiphysics)
• All structural and thermal capabilities
• (Other ANSYS licenses are supported for meshing only)

13. Getting started
• After starting ANSYS workbench
• Analysis System which includes different
Types of analysis like static structural, modal

14. Select required system
• Static structural analysis
• Sequence of operations like engineering
Data means material properties, geometry

15. Material properties

16. Geometry
• There are two options for geometry
1. Create geometry in ANSYS Design modeler
2. Import from other design software in particular format like
igs, step, etc.

19. Mesh and types

20. Meshing
• Initial Size Seed allows you to control the initial seeding of the mesh
size for each part.
• Smoothing attempts to improve element quality by moving
locations of nodes with respect to surrounding nodes and elements.
The Low, Medium, or High option controls the number of
smoothing iterations along with the threshold metric where the
mesher will start smoothing.
• Relevance Center sets the gauge of the Relevance slider control in
the Default group. Options are Coarse, Medium, and Fine. The
default value can be set automatically according to the Physics
Preference setting as described above under the Default Group.
• Element Size allows you to specify the element size used for the
entire model. This size will be used for all edge, face, and body
meshing.

21. • Transition affects the rate at which adjacent elements will grow.
Slow produces smooth transitions while Fast produces more abrupt
transitions.
• Span Angle Center sets the goal for curvature based refinement. The
mesh will subdivide in curved regions until the individual elements
span this angle. The following choices are available:
• Coarse - 91o to 60o
• Medium - 75o to 24o
• Fine - 36o to 12o
• Curvature Normal Angle is the maximum allowable angle that one
element edge is allowed to span.
• Proximity Accuracy allows you to control the accuracy level of
proximity size function calculations that are performed between
pairs of facets. For each pair, the proximity algorithm begins with a
base facet from which it determines a search range.

22. • Inflation is useful for CFD boundary layer resolution,
electromagnetic air gap resolution or resolving high stress
concentrations for structures. Inflation is supported for the
following mesh methods:
