Temperature

Modify the material definition to activate temperature dependence.

This step happens in addition the Specify a Reference Temperature step seen previously.

Open the file Tutorial_4.ans using a text editor.
Locate the HELIUS command. Specify an analysis temperature of 297.15 for the material environment by modifying Argument 8. It should appear as below:
```
HELIUSPFA,  9026,7,1,1,1,0,0,0,297.15,0,0,0,0,0.1,1.0E-06,0
```

Note: The text spacing may appear different depending on the ANSYS version used. The Material ID (9026) may also differ depending on your material library.
