Detailed Description

Functions to create instances of optimal subsidiary operators for the PseudoElasticPreconditioner.

Functions to create instances of optimal subsidiary operators for the PseudoElasticPreconditioner. By default we use hypre for the the elastic blocks but can use Trilinos ML too.
