[Trilinos-Users] LOBPCGSolMgr

[홍광우]

Hello Alicia,


I want to get the Ritz vectors and values when I use LOBPCGSolMgr.


Using LOBPCGSolMgr with BasicEigenproblem, I can get converged eigenvectors and eigenvalues (getSolution() function).


However, in the case that the iterative diagonalization does not converge for a given maximum number of iterations, I want to get unconverged Ritz vectors and values as well as converged eigenpairs.


The converged eigenpairs can be obtained using getSolution(), but I don't know how to get unconverged Ritz vectors and values using LOBPCGSolMgr.

Hello Kwangwong,



Why do you need the Eigensolver?  What are you trying to do with it?  I don't think you can access it directly, but we can probably come up with a different way to obtain the information you wanted to get out of it.



Best wishes,

Alicia

Dear Trilinos developers and users, 







Hello. I have a question about LOBPCGSolMgr. 







I want to get Eigensolver LOBPCG from LOBPCGSolMgr, but I don't know how to do. 







How can I get LOBPCG from LOBPCGSolMgr?
