Sorry for that Jose,

The last message I received says that:
[0]PETSC ERROR:   !
[0]PETSC ERROR: KSP did not converge (reason=DIVERGED_ITS)!

What could be the reason of not convergence, due to the fact that B matrix has 
some zero values on its diagonal? Is there any other methods which solves GEP 
even if there is zeros on diagonals?

Regards,
