Another, way to verify the solution of a numerical method is to examine the convergence of the solution as the mesh is refined. Generally, the numerical solution should converge to the exact solution as the mesh is refined. In order to refine the mesh, first click on the mesh tab, , in the tree outline. Next, expand "Sizing" in "Details of Mesh". The mesh will be refined by adjusting the "Element Size". The length of the beam is 4m so if you want n elements then you will need to set the "Element Size" to (4m/n). For instance, if you wanted 20 elements the "Element Size" should be set to (4m/20)=0.2m . After you have changed the "Element Size" to your preference, click on the solve button, , to recalculate the solution with the new mesh.
