Fig. 2: The nodal configuration of the cantilever beam  for d=0.5 (125 nodes, 221 collocation points)
Fig. 6: The convergence rate in the cantilever beam  under the end load
Fig. 12 shows convergence rate with three regular nodal  configurations (n =53, 183, and 721) and three irregular  nodal configurations (n  =49, 179, and 657)
