162 • Using ansys for finite element analysis
Step-by-Step ANSYS Solution
Preprocessing: Defining the Problem

1. Enter ANSYS in the working directory specified by your instructor
using “pipe-th” as the jobname.
2. Set the GUI Preferences to Thermal:
Main Menu > Preferences … Select “Thermal”, then [OK]
3. Read input from “pipe-th.inp” to create the 2D axisymmetric model
and specify mesh divisions on lines:
Utility Menu > File > Read Input from … Select “pipe-th.inp”, then
[OK]
Or issue:/INPUT,pipe-th,inp

Note: The input file is given at the end of the tutorial. Type it using
any text editor or give input directly in PREP.
4. Specify the element type to be PLANE55 and set keyopt(3) =
axisymmetric:
Main Menu > Preprocessor > Element Type > Add/Edit/Delete …
[Add ...]
Pick “Thermal Solid” and “Quad 4node 55”, then [OK] [Options ...]
Set K3 = Axisymmetric, then OK] [Close]
Or issue: ET, 1, PLANE55,,, 1
