Detailed Description

Preconditioner state for the LSC factory.

Preconditioner state for the LSC factory. This is based on the notation and concepts found in

Elman, Howle, Shadid, Silvester, and Tuminaro, "Least Squares Preconditioners for Stabilized Discretizations of the Navier-Stokes Euqations," SISC-2007.
