[Trilinos-Users] customizing Belos residual tests

Hi all,

I would like to compare the convergence and performance of
Belos to some native solvers in an application.
To do that I would like to use the BlockCGSolMgr and a convergence criterion

||A*x-b||_2 / (||A||_F ||x||_2 + ||b||_2) < tol

Is that possible without hacking in the Belos source itself?

Thanks!
Jonas
