Now pimpleDyMFoam is exactly equivalent to pimpleFoam when running on a

staticFvMesh is automatically constructed so that the pimpleDyMFoam solver can
run any pimpleFoam case without change.

The patch magSf calculation has been changed so that it uses the same
triangulation as the overlap algorithm. This improves consistency and
means that for exactly conforming patches (typically before any mesh
motion) the weights do not require normalisation.

ENH: compressibleInterFoam family: merged two-phase momentum stress modelling from compressibleInterPhaseTransportFoam

The new momentum stress model selector class
compressibleInterPhaseTransportModel is now used to select between the options:

Description
    Transport model selection class for the compressibleInterFoam family of
    solvers.

    By default the standard mixture transport modelling approach is used in
    which a single momentum stress model (laminar, non-Newtonian, LES or RAS) is
    constructed for the mixture.  However if the \c simulationType in
    constant/turbulenceProperties is set to \c twoPhaseTransport the alternative
    Euler-Euler two-phase transport modelling approach is used in which separate
    stress models (laminar, non-Newtonian, LES or RAS) are instantiated for each
    of the two phases allowing for different modeling for the phases.

Mixture and two-phase momentum stress modelling is now supported in
compressibleInterFoam, compressibleInterDyMFoam and compressibleInterFilmFoam.
The prototype compressibleInterPhaseTransportFoam solver is no longer needed and
has been removed.

Another exception has been added to globalIndexAndTransform to prevent
transformations being generated from coupled patch pairs marked with
coincident-full-match transformations. Foamy generates such patches, and
the faces on them at intermediate stages of meshing can be degenerate,
making the calculation of transformations unreliable. This change
enforces the definition that coincident-full-match patch pairs are not
transformed.

In the event that matching centroids across a coupled patch pair fails,
we fall back to matching the face point average. The latter can be
obtained more reliably on degenerate faces as the calculation does not
involve division by the face area.

This fallback was already implemented as part of processorPolyPatch.
This change also applies it to the faceCoupleInfo class used by
reconstructParMesh.

ENH: compressibleInterPhaseTransportFoam: New variant of compressibleInterFoam supporting separate phase stress models

In this version of compressibleInterFoam separate stress models (laminar,
non-Newtonian, LES or RAS) are instantiated for each of the two phases allowing
for completely different modeling for the phases.

e.g. in the climbingRod tutorial case provided a Newtonian laminar model is
instantiated for the air and a Maxwell non-Newtonian model is instantiated for
the viscoelastic liquid.  To stabilize the Maxwell model in regions where the
liquid phase-fraction is 0 the new symmTensorPhaseLimitStabilization fvOption is
applied.

Other phase stress modeling combinations are also possible, e.g. the air may be
turbulent but the liquid laminar and an RAS or LES model applied to the air
only.  However, to stabilize this combination a suitable fvOption would need to
be applied to the turbulence properties where the air phase-fraction is 0.
