Assignment$-3$

Find the temperature at interior nodes of the plate $4040cm$ with thermal conductivity of $k=0\mathrm{.}49Ca\frac{l}{s}.cm.C,$ as shown in fig$\mathrm{.}1.$ Continue the iteration until the error drops to less than $1\%$ at all nodes. You can use relaxation factor of $1\mathrm{.}5$

Also determine the heat flux and direction at each node
