[petsc-users] Convergence_Eigenvalues_k=3

[Oo]

Hi,


For analysis the convergence of linear solver, 
I meet a problem.


One is the list of Eigenvalues whose linear system which has a convergence solution.
The other is the list of Eigenvalues whose linear system whose solution does not converge (convergenceReason=-3).


Do you know what kind of method can be used to obtain a convergence solution for our non-convergence case?


Thanks,


Meng
