Basic Tutorials

The following documents will lead you through several example problems using ANSYS. ANSYS 7.0 was used to create some of these tutorials while ANSYS 5.7.1 was used to create others, therefore, if you are using a different version of ANSYS make note of changes in the menu structure. Complete these tutorials in order as each tutorial will build on skills taught in the previous example.

• Two Dimensional Truss
  Basic functions will be shown in detail to provide you with a general knowledge of how to use ANSYS. This tutorial should take approximately an hour and a half to complete.
• Bicycle Space Frame
  Intermediate ANSYS functions will be shown in detail to provide you with a more general understanding of how to use ANSYS. This tutorial should take approximately an hour and a half to complete.
• 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.

Installing ansys 10 on windows 7 32 bit.

The main issue on windows 7 that  i have found is that license server does not start automatically so we have to start it manually. to start it manually  create bat file ansys.bat and place this file in location 

C:\Program Files\Ansys Inc\Shared Files\Licensing\intel

and license.dat file must be copied in two locations

C:\Program Files\Ansys Inc\Shared Files\Licensing\intel

and

C:\Program Files\Ansys Inc\Shared Files\Licensing

now first run ansys.bat after it ansys shortcut

you will be able to run ansys on windows 7 ..

create ansys.bat 

***********************************

Open Notepad in Windows. Notepad will allow you to create a file without unnecessary coding. You can do this by navigating to Start -> Programs -> Accessories -> Notepad.
Save your file before you get started. This will prevent your work from being a totally lost later.
 Click File -> Save, and choose a ansys.bat
 Save the file in C:\Program Files\Ansys Inc\Shared Files\Licensing\intel
Click the dropdown menu under "Save as type" and select "All files" instead of Text (.txt).
 End the file name with .bat as the extension. For instance, you might save a ansys file as "ansys.bat".
  Click Save. If you did this correctly, you should see your file name in the title bar of Notepad.

 and the icon of this file look like

now right click on this ansys file and copy paste the commands given below in this file and save this file.
