Solve the Poisson's equation $\nabla^2 f = xy$ and $f = 2$ on boundary by assuming square domain $0 \leq x \leq 3$ and $0 \leq y \leq 3$ and $h = 1$ . [5]

Solve the Poisson's equation $\nabla^2 f = xy$ and $f = 2$ on boundary by assuming square domain $0 \leq x \leq 3$ and $0 \leq y \leq 3$ and $h = 1$. [5]

PDE: $\nabla^2 f = xy$ - Boundary condition: $f = 2$ on all boundaries - Domain: $0 \le x \le 3$ , $0 \le y \le 3$ - Step size: $h = 1$ Grid points at $x = 0,1,2,3$ and $y = 0,1,2,3$ . Interior nodes at $(1,1),(2,1),(1,2),(2,2)$ . $f{i-1,j} + f{i+1,j} + f{i,j-1} + f{i,j+1} - 4f{i,j} = h^2 (xy)$ ...
