Figs. 13 (a) B4L1 and (b) B4L2 show SFEM is uneven initially. Based on Fig. 13 (a) B4L1, the line of SFEM is wavy from starting point to point 0.25. Then, the line became smooth as Newman & Raju 1979. In Fig. 13 (b) B4L2, a similar observation is made from start to point 0.25, but the end of the line increased starting at point 0.78. The cause was probably due to the re-meshing process. However, both gradually improve after point 0.22 as both methods are in good agreement, as shown in the graph. The RMSE value for both graphs is calculated to be 0.1496.
