Step 1: Import Required Libraries

import numpy as np

import matplotlib.pyplot as plt

Step 2: Specify the Parameters and Initial Conditions

# Parameters

L = 1.0      # Length of the rod

T = 0.5      # Total time

nx = 50      # Number of spatial points

nt = 1000    # Number of time steps

alpha = 0.01 # Thermal diffusivity

# Discretization

dx = L / (nx – 1)

dt = T / nt

# Stability condition

if dt > dx**2 / (2 * alpha):

raise ValueError(“Stability condition violated: dt must be less than dx^2 / (2 * alpha)”)

# Initial condition: u(x,0) = sin(pi * x)

x = np.linspace(0, L, nx)

u = np.sin(np.pi * x)

# Boundary conditions: u(0,t) = u(L,t) = 0

u[0] = u[-1] = 0

Step 3: Time-Stepping Loop

# Time-stepping loop

u_new = np.zeros(nx)

for n in range(nt):

for i in range(1, nx-1):

u_new[i] = u[i] + alpha * dt / dx**2 * (u[i+1] – 2*u[i] + u[i-1])
