ANSYS quote: "they appear graphically equal and the criteria from 1A and 1B have been met. However, convergence must be verified graphically. Figure 5 shows a plot of the convergence from the table above. Note that the curve has not visually flattened out and that there is still a 21% error between the final average value of 124,099PSI and the previous hand calculations of 156,849PSI. Note that this method of meshing and iteration resulted in no mesh quality errors or warnings and met our main accuracy criteria, yet an error still exists in the model. This method of meshing was performed to illustrate a point. Often in a solid mesh there can exist very poorly shaped elements just below the surface although the number of elements along the surface appear adequate to ensure an accurate solution"
