Verification and Validation
Verification
One of the ways we can verify our data is by refining the mesh. Open up the mesh, and increase the Number of Divisions for Edge Sizing and Edge Sizing 2 to 100
. Click Mesh in the Outline window, and in the Details window, expand statistics. The number of elements should now be 40000. Exit out of the mesher, and click
To validate our data, we will take a compare the data from actual experiment. Much thanks to David Caughey for providing us with the experimental data.
