Hello,

I've used Boomeramg as a preconditioner.

Now, I am wondering whether I can use Boomeramg as a solver ? and is it possible that I use Boomeramg as both a preconditioner and a solver?

I saw one slide saying that I can use KSPSetType(ksp, KSPRICHARDSON);

But when I try it and use -ksp_view, it shows that my solver is Richardson not Boomeramg.

Could u clarify this issue ?

Thank you.
