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 expand the mesh tab, , in the tree outline. Next, expand click on "Edge Sizing", Image Added, such that it highlights blue. Now, change the number of divisions in the "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 "Edge Sizing"" table. Remember, that each line segment of the plane frame structure will be divided in to the number of divisions that you specify. After you have changed the "Element Size" to your preference, click on the solve button, Image Modified, to recalculate the solution with the new mesh.
