Governing equation

\nabla^{2} u = 0 \Rightarrow u_{i, j} = \frac{1}{4} (u_{i - 1, j} + u_{i + 1, j} + u_{i, j - 1} + u_{i, j + 1}), 100 \times 100 grid, r = 0.00 e + 0

Reading this result: At steady state ∇²u=0 means every interior cell equals the average of its four neighbors, so heat spreads smoothly between the fixed hot and cold edges.
