We have the following Poisson equation. u(x)=cos(x)u(0)=2u(5)=0for0x5 1) Develop the finite-difference equations for the above PDE using a uniform mesh, and write a computer program
We have the following Poisson equation. u(x)=cos(x)u(0)=2u(5)=0for0x5 1) Develop the finite-difference equations for the above PDE using a uniform mesh, and write a computer program to solve the resulting algebraic equations using the Jacobi method. Use 101 grid points. Use an absolute convergence tolerance of 105. 2) Repeat 1), but now using the Gauss-Seidel method. 3) Repeat 1), but now using a Conjugate Gradient (CG) method (or its variants). 4) On a single graph, plot the residuals for the Jacobi, Gauss-Seidel, and CG methods. Discuss your results. Your comments should touch upon issues such as convergence, ease of implementation, and other issues that you may deem relevant
