For this static structural problem, the maximum bending stress is of interest. In order to examine the maximum bending stress first expand the Beam Tool folder,

By default, ANSYS averages the stress values over the length of the beam. Using only two elements, this yields a minimum value of 2.3176e6 Pa for the maximum bending stress. This is an error created by the small number of elements used. The minimum value of maximum bending stress should be zero because there is no moment where the force is applied. To correct this error, we will display the unaveraged results. To do so, look in the "Details of "Maximum Bending Stress"" window in the lower left corner of the window. Expand "Integration Point Results", if it is not already, and change the "Display Option" from Averaged to Unaveraged, as seen below.
The following output should be obtained, with a correct minimum value of zero.
