Step 9: Validate the results
It is very important that you take the time to check the validity of your solution. This section leads you through some of the steps you can take to validate your solution.
Simple Checks
Does the deformed shape look reasonable and agree with the applied boundary conditions? We checked this in step 8.
...
Select All struc forc F for Item to be listed and click OK. The forces in the X and Z directions are essentially zero and the total Y-reaction is 100.00 (lbf) as expected.
Refine Mesh
Let's repeat the solution on a finer mesh with more divisions in the z-direction. Repeat the mesh steps for the MESH200 element, but this time use smart size 3 and element size of 0.08. Repeat the mesh steps for the SOLID45 element and set the element edge length to 0.05 instead of 0.125. This will create 10 divisions through the thickness of the crank instead of 4. When warned that the picked volumes are already meshed, check Yes and click OK to remesh.

The maximum displacement at the tip of shaft is 1.8% greater and the maximum stress is 7.0% less at the upper-left corner of the cutout. We need to further refine the mesh to validate the solution.
