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

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)?

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:

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,

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:


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

that uses this functionality.

thanks David
