The maximum displacement at the tip of shaft is 1.99% 9% greater and the maximum stress is 0.49% greater at the upper-left corner of the cutout10% greater. This indicates that the solution we have obtained is reasonably independent of still dependent on the mesh. We would need to further refine the mesh. Do keep in mind that one would have to make more detailed comparisons between the solutions on the two meshes before we can make a definitive statement about the mesh independence of our results.
