[Trilinos-Users] [EXTERNAL] Belos::SolverManager::setUserConvStatusTest()

[Thornquist, Heidi K]

Hi David,

In Belos, the PseudoBlockGmresSolMgr also allows for a user-defined status test.  This is an idea we have played with migrating throughout Belos, is there a certain solver that you are interested in changing the stopping criteria (status test)?

Thanks,
Heidi

Hello David,

I don't think we have any Belos examples with the functionality you want, but we do have an Anasazi example that uses a custom status test:
https://trilinos.org/docs/dev/packages/anasazi/doc/html/LOBPCGCustomStatusTest_8cpp-example.html

Even though Belos and Anasazi solve different types of problems, they're structurally very similar.  Please let us know if you have any further questions.

Best wishes,
Alicia

Hi,



We have a summer student who wants to do some experimentation

with iterative solvers. She needs to set her own convergence test.

I found that this is possible:

Belos::SolverManager::setUserConvStatusTest().

It would be a great help if you could point me to an example

that uses this functionality.



thanks David
