CONTENTS

1. ANSYS Utilities
An introduction to using ANSYS. This includes a quick explanation of the stages of analysis, how to start ANSYS, the use of the windows in ANSYS, convergence testing, saving/restoring jobs, and working with Pro/E.

- Introduction to Finite Element Analysis
A brief introduction of the 3 stages involved in finite element analysis.

- Starting up ANSYS
How to start ANSYS using windows NT and Unix X-Windows.

- ANSYS Environment
An introduction to the windows used in ANSYS

- ANSYS Interface
An explanation of the Graphic User Interface (GUI) in comparison to the command file approach.

- Convergence Testing
This file can help you to determine how small your meshing elements need to be before you can trust the solution.

- Saving/Restoring Jobs
Description of how to save your work in ANSYS and how to resume a previously saved job.

- ANSYS Files
Definitions of the different files created by ANSYS.

- Printing Results
Saving data and figures generated in ANSYS.

- Working with Pro Engineer
A description of how to export geometry from Pro/E into ANSYS.

2. Basic Tutorials

Detailed tutorials outlining basic structural analysis using ANSYS.
- Two Dimensional Truss
Basic functions will be shown in detail to provide you with a general knowledge of how to use ANSYS.

- Bicycle Space Frame
Intermediate ANSYS functions will be shown in detail to provide you with a more general understanding of how to use ANSYS.

- Plane Stress Bracket
Boolean operations, plane stress and uniform pressure loading will be introduced in the creation and analysis of this

2-Dimensional object.

- Solid Modeling
This tutorial will introduce techniques such as filleting, extrusion, copying and working plane orienation to create

3-Dimensional objects.

3. Intermediate Tutorials

Complex skills such as dynamic analysis and nonlinearities are explored in this section.

- Effect of Self Weight
Incorporating the weight of an object into the finite element analysis is shown in this simple cantilever beam example.

- Distributed Loading
The application of distributed loads and the use of element tables to extract data is expalined in this tutorial.

- NonLinear Analysis
A large moment is applied to the end of a cantilever beam to explore Geometric Nonlinear behaviour (large deformations).

There is also an associated tutorial for an explanation of the Graphical Solution Tracking (GST) plot.

- Buckling
In this tutorial both the Eigenvalue and Nonlinear methods are used to solve a simple buckling problem.

- NonLinear Materials
The purpose of the tutorial is to describe how to include material nonlinearities in an ANSYS model.

- Dynamic Analysis
These tutorial explore the dynamic analyis capabilities of ANSYS. Modal, Harmonic, and Transient Analyses are shown in detail.

- Thermal Examples
Analysis of a pure conduction, a mixed convection/conduction/insulated boundary condition example, and a transient heat onduction analysis.

- Modelling Using Axisymmetry
Utilizing axisymmetry to model a 3-D structure in 2-D to reduce computational time.

4. Advanced Tutorials

Advanced skills such as substructuring and optimization are explored in this section.

- Springs and Joints
The creation of models with multiple elements types will be explored in this tutorial. Additionally, elements COMBIN7 and COMBIN14 will be explained as well as the use of parameters to store data.

- Design Optimization
The use of Design Optimization in ANSYS is used to solve for unknown parameters of a beam.

- Substructuring
The use of Substructuring in ANSYS is used to solve a simple problem.

- Coupled Structural/Thermal Analysis
The use of ANSYS physics environments to solve a simple structural/thermal problem.

- Using P-Elements
The stress distribution of a model is solved using p-elements and compared to h-elements.

- Melting Using Element Death
Using element death to model a volume melting.

- Contact Elements
Model of two beams coming into contact with each other.

- ANSYS Parametric Design Language
Design a truss using parametric variables.

5. Postprocessing Tutorials

Postprocessing tools available in ANSYS such as X-sectional views of the geometry are shown in this section.

- Viewing Cross Sectional Results
The method to view cross sectional results for a volume are shown in this tutorial.

- Advanced X-Sectional Results: Using Paths to Post Process Results
The purpose of this tutorial is to create and use ‘paths’ to provide extra detail during post processing.

- Data Plotting: Using Tables to Post Process Results
The purpose of this tutorial is to outline the steps required to plot results using tables, a special type of array.

- Changing Graphical Properties
This tutorial outlines some of the basic graphical changes that can be made to the main screen and model.

6. Command Line Files
Example problems solved using command line coding only, in addition to several files to help you to generate your own command line files.

- Creating Command Files
Directions on generating and running command files.

- ANSYS Command File Programming Features
