It can be seen from Table 1 and Table 2 that the calculated numerical solution will infinitely approach the exact solution with continuous grid subdivision. And then verified the correctness and feasibility of the program.
From Tables 1 and 2, it can be seen that the calculated numerical solution will infinitely approach the exact solution as the grid is continuously divided. Furthermore, the correctness and feasibility of the program were verified.
As can be seen from Table 1 and Table 2, the calculated numerical solution will approach the exact solution infinitely with the continuous mesh generation. Then the correctness and feasibility of the program are verified.
