Obtaining the steady state solution of the 1-D heat conduction equations using FTCS Method.

1-D heat equation is solved and contour plot is presented for both FTCS and analytical solution

We are interested in obtaining the steady state solution of the 1-D heat conduction equations using FTCS Method.
And boundary conditions are: T=300 K at x=0 and 0.3 m and T=100 K at all the other interior points.
α = 〖3*10〗^(-6) m-2s-1
. Here, t=30 minutes, ∆x=0.015m and ∆t=20 sec
