One can think of Verification and Validation as a formal process for checking results. Each of these terms has a specific meaning which we won't get into here. We have already done some checks on the ANSYS results by comparing them to the hand calculations and checking that the ANSYS solution agrees with the appropriate traction or displacement boundary condition at each boundary. Let's next check the ANSYS's displacement value at the right boundary with the value in our the hand calculations.

Check Displacement Value at the Right Boundary

...

I get a value around 0.045 mm at the right end which . This is about a 10% deviation from the hand calculation result of 0.05 mm we obtained in our Pre-Analysis. This is a reasonable agreement considering that the hand calculation ignores the high stress areas at the left and right ends. But these high stress areas (both tensile and compressive) affect relatively small areas of the model and so don't contribute a lot to the overall displacement.
