Define the Mesh

1. Right-click on Mesh Model and choose Edit.
2. Type 0.09 in the Element Size field under Global Settings.
3. Select Linear from the Element Order drop-down. Linear elements are good for thermal analysis.

   

   You are using linear solid elements because there is no need for midside nodes in heat transfer analysis.

4. Click OK.
5. After the mesh is generated, the model should look as shown below.
