Meanwhile, the graph for SFEM is unsynchronized with the Newman & Raju 1979 graph, although both graphs represent good agreement, as illustrated by Figs. 14 (a) B5L1 and (b) B5L2. The RMSE value for both graphs is calculated to be 0.1496. It can be deducted that the limitation of the simulation and re-meshing time of the simulation contributes to the initially un-uniform line produced by the graph.
