To disable face correspondence checking set
checkFaceCorrespondence off;
in blockMeshDict. This is necessary in the rare cases where adjacent block
faces do not need to correspond because they are geometrically collapsed,
e.g. to form a pole/axis.

ENH: foamyHexMesh: Made default region volume type that of it's parent
Foamy surface conformation entries have a "meshableSide" entry which
controls which side of the surface is to be meshed. Typically this is
set "inside" for boundaries and "both" for baffles. A sub-region's
default entry is now taken from it's parent, rather than a specific
value (it was "inside"). This is consistent with how other entries are
handled.

ENH: foamyHexMesh: Added (reinstated) baffle patches
A patch can now be assigned to a baffle surface. This assignment will
take precedence over any face-zones.

STYLE: foamyHexMesh: Switched off output of all the secondary meshes
The integration of force and heat transfer onto the particle is
facilitated by a run-time-selectable integration scheme. These schemes
were written to generate the value at the end of an intregration step
and also an average value over the step from which the total transfer
was computed.
The average value in the Euler scheme was implemented incorrectly, which
resulted in the momentum and heat transfer processes being
non-conservative. Implementing the average correctly, however, would
have inteoduced a number of trancendental functions which would have
negated the purpose of the Euler scheme as the cheap and stable option.
The schemes have been rewritten to generate changes over the step,
rather than the final value. This change is then used to calculate the
transfers. Regardless of the scheme, this formulation is guaranteed to
be conservative, and the Euler scheme remains computationally
inexpensive.

ENH: integrationSchemes: Further simplification and optimisation
Removed templating from integration schemes, improved the name
convention, and optimised the utilisation so that the virtual call is
only made once per integration in the KinematicParcel and the
ThermoParcel.
BUG: integrationSchemes: Corrections to coupled/non-coupled force splitting
The integration splitting implemented in commit a5806207 has been shown
to be incorrect in some cases. A new procedure has been implemented
which can correctly split the implicit-explicit integral into a number
of pieces, in order to calculate the contribution of each. This is
intended for integrating coupled and non-coupled particle momentum and
heat transfers.
However, currently there is only ever one implicit coefficient used in
these transfers (there is no implicit non-coupled contribution). The
evaluation has therefore been short-cutted to only do the integration
with respect to the coupled contributions. The splitting functionality
has been retained in case additional separate implicit coefficients are
required in the future.

XiEngineFoam is a premixed/partially-premixed combustion engine solver which
exclusively uses the Xi flamelet combustion model.
engineFoam is a general engine solver for inhomogeneous combustion with or
without spray supporting run-time selection of the chemistry-based combustion
model.
Standard crank-connecting rod and the new free-piston kinematics motion options
are provides, others can easily be added.

- added an explicit print, but only report profiling to the log
file from master process.
We don't wish to overwrite any profiling that was conducted during
the simulation. Besides which, we don't have a proper Time object
for handling the write nicely either.
- add note in BuildIssues about the I_MPI_CC variable, which is needed
when building with Intel-MPI and gcc/clang.
This additional setting is needed since the changes needed to solve
the issue of building scotch with Intel-MPI and icc (issue #434)
means that mpiicc is now being used as the wrapper when compiling
scotch.
- have the FOAM_MPI short name for INTELMPI start with 'impi-' instead
of just the version number.
Intel-MPI is often installed as /opt/intel/impi/4.1.3.049, which
results in 'FOAM_MPI=4.1.3.049' and the mpi flavour is lost.
Prefix these cases with 'impi-'
- csearch(), search(), csearchScoped(), searchScoped() methods
can be used to find an entry and also retain the enclosing
dictionary context.
- To avoid ambiguity between a dot (.) as a scoping character and
legal part of a keyword, entries can now be accessed directly using
slash-scoping semantics similar to file-names:
* cfindScopedDictPtr, findScopedDictPtr
- To get or create a sub-dictionary entry:
* makeScopedDictPtr, which behaves similarly to mkdirp in that it
will create any intermediate dictionaries as required.
