Hi,
I found an very easy example on
trilinos-11.0.3-Source/packages/aztecoo/example/AztecOO/cxx_main.cpp
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
converge.
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
do.
