1.Develop a computer program using the fully implicit scheme and Gauss–Seidel method. Redo with refined grid size distributions as 4 4, 6 6 and 8 8 using this code.

(a) Present temperature distribution along with percent relative error for the vertical center line with refined grid size distributions at the fifth time step.

(b) Show the temperature distribution for the vertical center line with increase in time for the grid of 8 8.

2. Develop a computer program using the fully implicit scheme and lineby-line method. Repeat using this code.
