We have a plate of 12 x 9 cm and the temperatures on the edges are held as shown in the sketch. Take Az = 4y = 3 cm and use the S.O.R. method (successive overrelaxation method) to find the temperatures at all the grid-points. First calculate the optimal value of w and then use this value in the algorithm. 100 90 70 500 (Not to scale!) 100 70 50 30 We have a plate of 12 x 9 cm and the temperatures on the edges are held as shown in the sketch.
