Verification & Validation
Refine the Mesh
One of the ways we can check the validity of our analysis is by refining our mesh. If the values for our frequencies approach a limit, then we have arrived at our answer. If the values change drastically when we refine the mesh, then we need to refine the mesh further and we have not yet found an acceptable solution. We will refine the mesh by increasing the number of divisions in our edge sizing. In the Outline window, go to Mesh > Edge Sizing > Number of Divisions > 100
. Also, go to Mesh > Edge Sizing 2 > Number of Divisions > 40
. Our new mesh looks like this:
...
Mode Number | Frequency (Unrefined Mesh) | Frequency (Refined Mesh) |
---|---|---|
1 | 4.8329 | 4.8329 8297 |
2 | 25.327 | 25.327 236 |
3 | 32.175 | 32.175 155 |
4 | 38.089 | 38.089 038 |
5 | 48.315 | 48.315 063 |
6 | 53.540 | 53.540 403 |
Because the values don't change much, we don't have to refine the mesh further. We are done!
