Now let's verify that this solution is mesh converged. To do so, we will have ANSYS refine the mesh until the change in a chosen criteria is less than a specified percent difference. In this example, the criteria we will examine is the maximum value of the von Mises Stress. From the tree on the left, right-click Equivalent (von Mises) Stress > Insert > Convergence. Set the Allowable Change to 5%, as seen below.

Next, click Solve in the top toolbar. It turns out that ANSYS only needs one iteration to reach the Allowable Change. After one iteration, we see that there is a change of 0.12% in the maximum von Mises Stress in the plate. From this, we can conclude that our solution is mesh converged. Next, right click on Convergence in the tree on the left and choose Delete. This is done to speed up the optimization process, which will now move onto.
