Hello,

Could you please see the attached question?

Given: January 6, 2017 Due: February 6, 2017 1: 4, 11, 13. A rectangular trough of infinite length and cross sectional dimensions of alpha = 1.0 cm, b = 2.0 cm, is shown in the figure. Three sides are grounded, and the top side is held at V_0 = 100 V. (a) Write a fortran or C + + program to solve Laplace's equation using the finite element method. Divide the region into 50 equally sized triangles. If it is useful to you, a fortran matrix inversion subroutine is attached. (b) Compare the finite element solution to the exact solution(found via separation of variables in rectangular co-ordinates)of V(x, y) = 4V_0/pi sigma^infinity_k = 0sin n pi x/a sin h n pi y/b sin h n pi a/b, n = 2k + 1
