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.
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.
This allows polynomial functions for e.g. velocity to be specified in the uniformFixedValue BC
Consider a linear function for Ux(t) with Uy and Uz = 0:
inlet
{
type uniformFixedValue;
uniformValue polynomial
(
((10 0 0) (0 0 0))
((100 0 0) (1 0 0))
);
}

Currently these vectors are generated at the same time as the wall-distance field
by the same run-time selected algorithm. This will be changed so that the wall-reflection
vectors are only generated and stored if required.
When using models which require the wallDist e.g. kOmegaSST it will
request the method to be used from the wallDist sub-dictionary in
fvSchemes e.g.
wallDist
{
method meshWave;
}
specifies the mesh-wave method as hard-coded in previous OpenFOAM versions.

Note:
In order to avoid unexpectedly poor results I think it would be
better if sub-cycling in time were limited to static meshes and
solid-body motion only and the Vsc() function removed and I will
consider this for the next release with the addition of a check for
solid-body motion in the case that sub-cycling is applied. Now that
MULES support semi-implicit operation there is less need for
sub-cycling and I would recommend that you use this approach in
interDyMFoam for your complex mesh motion cases.
