a 1D domain with length L subjected to heat flux Q from top while a heat sink boundary condition is assumed at the bottom. The domain is discretised uniformly using linear elements with length r. Contour plot of percentage error calculated by comparing analytical and numerical solutions for the peak temperatures obtained at \(x=L\) with b time step \(\Delta t=t_h/50\) and c \(\Delta t=t_h/5\)
