Verification and validation can be thought as a formal process for checking results. Each of these terms has a specific meaning which we won't get into here. The only verification check discussed below is the effect of mesh refinement.

Refine Mesh

To change the mesh size, go back to Mesh > Edge Sizing in the tree and change the Number of Divisions appropriately. Click Solve. All results will be updated for the new mesh. Then, export the results for the temperature along the y=1 path to Excel or MATLAB. In Excel or MATLAB, make a plot showing T vs. x along y=1 for different meshes. You should find that the temperature variation along this line becomes independent of the mesh as the mesh gets finer. In fact, for this problem, it turns out we don't need a lot of elements to get a result that is nearly independent of the mesh.
