bvp_05_test: FENICS/Python version Solve -u" + u = x, 0 < x < 1 u(0) = 0 u(1) = 1-cosh(1)/sinh(1) Exact solution: u(x) = x - sinh(x)/sinh(1) Notice Neumann condition on the right. Calling FFC just-in-time (JIT) compiler, this may take some time. Solving linear variational problem. Graphics saved as "bvp_05_solution.png" bvp_05_test: Normal end of execution.
