Classes
class	oomph::FpPreconditionerAssemblyHandler
	A class that is used to define the functions used to assemble the elemental contributions to the pressure advection diffusion problem used by the Fp preconditioner. More...

class	oomph::FpPressureAdvectionDiffusionProblem< ELEMENT >
	Auxiliary Problem that can be used to assemble the pressure advection diffusion matrix needed by the FpPreconditoner. More...

class	oomph::NavierStokesSchurComplementPreconditioner
	The least-squares commutator (LSC; formerly BFBT) Navier Stokes preconditioner. It uses blocks corresponding to the velocity and pressure unknowns, i.e. there are a total of 2x2 blocks, and all velocity components are treated as a single block of unknowns. More...

class	oomph::NavierStokesExactPreconditioner< MATRIX >
	The exact Navier Stokes preconditioner. This extracts 2x2 blocks (corresponding to the velocity and pressure unknowns) and uses these to build a single preconditioner matrix for testing purposes. Iterative solvers should converge in a single step if this is used. If it doesn't something is wrong in the setup of the block matrices. More...
