Solve the steady state heat equation to get the temperature profile for a square rod ( 1mx1m) for y=x= 0.1m. Assume that the slab has a temperature maintained around the boundary as shown below: a Give the finite difference equation to solve for T(x,y) and draw the node diagram. Hint: use the "central difference" form. b. Solve for and plot T(xy). Hint, when you input the equation into the first cell, you should have "guess" temperature values in the rest of the cells. Slowly drag the cell across a row and then down the columns with the "enable iteration" already checked (File Options Formulas check "Enable iterative calculation"). c. Inside the plate, what is the lowest temperature? Solve the steady state heat equation to get the temperature profile for a square rod ( 1mx1m) for y=x= 0.1m.
