a6dded3ba5 twoPhaseEulerFoam: Add partial-elimination to phase flux and velocity correction 
Improves stability and convergence of systems in which drag dominates
e.g. small particles in high-speed gas flow.

Additionally a new ddtPhiCorr strategy is included in which correction
is applied only where the phases are nearly pure.  This reduces
staggering patters near the free-surface of bubble-column simulations.

afcd290d75 Solvers based on p_rgh: Added support for optional hRef 
Allows the specification of a reference height, for example the height
of the free-surface in a VoF simulation, which reduces the range of p_rgh.

hRef is a uniformDimensionedScalarField specified via the constant/hRef
file, equivalent to the way in which g is specified, so that it can be
looked-up from the database.  For example see the constant/hRef file in
the DTCHull LTSInterFoam and interDyMFoam cases.

f78d33b634 interFoam family: Add support for MULES-bounded Crank-Nicolson 2nd-order ddt(alpha) 
This is an experimental feature demonstrating the potential of MULES to
create bounded solution which are 2nd-order in time AND space.

Crank-Nicolson may be selected on U and/or alpha but will only be fully
2nd-order if used on both within the PIMPLE-loop to converge the
interaction between the flux and phase-fraction.  Note also that
Crank-Nicolson may not be used with sub-cycling but all the features of
semi-implicit MULES are available in particular MULESCorr and
alphaApplyPrevCorr.

Examples of ddt specification:

ddtSchemes
{
    default         Euler;
}

ddtSchemes
{
    default         CrankNicolson 0.9;
}

ddtSchemes
{
    default         none;
    ddt(alpha)      CrankNicolson 0.9;
    ddt(rho,U)      CrankNicolson 0.9;
}

ddtSchemes
{
    default         none;
    ddt(alpha)      Euler;
    ddt(rho,U)      CrankNicolson 0.9;
}

ddtSchemes
{
    default         none;
    ddt(alpha)      CrankNicolson 0.9;
    ddt(rho,U)      Euler;
}

In these examples a small amount of off-centering in used to stabilize
the Crank-Nicolson scheme.  Also the specification for alpha1 is via the
generic phase-fraction name to ensure in multiphase solvers (when
Crank-Nicolson support is added) the scheme is identical for all phase
fractions.
