[Trilinos-Users] null space removal

[Heroux, Michael A]

Hi Chris,

This is something I have wanted to add for a long time, but as far as I know it is not generally available.  ML provides this capability itself, if you are using it.  It would be fairly straight-forward to add this.  Can you describe your specific situation?

Thanks.

Mike

Is there a way to automatically remove a known null space during an iterative solve?  Dare I say, similar to KSPSetNullSpace in Petsc.  Or is the preferred method user implementation of a projection operator?

Thanks,

Chris
