I found an very easy example on

I tried to execute it but I am not sure the correct solution for example.
Can I find the correct solution?

One more question is that on my computer, that iteration was not converged.
Here is last few sentences



Blah blah..

iter:  100           residual = 7.795092e-02





           Warning: maximum number of iterations exceeded

           without convergence


           Solver:                        gmres

           number of iterations:      100


           Recursive residual =  2.8463e+01


           Calculated Norms
Requested Norm



           ||r||_2 / ||r0||_2:               7.795092e-02      1.000000e-08






                     Solution time: 2.532604 (sec.)

                     total iterations: 100

Solver performed 100 iterations.

Norm of true residual = 28.4635



Is it correct one? I don't think developer gave us the example that does not

If you know correct answer, please let me know and also I very welcome some
pieces of advice to the possible source of error that new comer might easily
