Reduce the number of phaseSystems libraries:
- phaseSystems previously had a number of smaller libraries to provide
interface and model properties, etc. This potential flexibility was
never actually used anywhere, but causes cyclic dependencies between
phaseSystem and the models (and turbulence) that causes extreme
difficulty for mingw linking (issue #1238).

Avoid duplicate symbol for phaseCompressibleTurbulenceModels
Common turbulence models are defined in libreactingMultiphaseSystem,
and libmultiphaseReactingTurbulenceModels is now redundant.
The libtwoPhaseReactingTurbulenceModels extends the common models
for reactingTwoPhaseSystem.
- previously introduced `getOrDefault` as a dictionary _get_ method,
now complete the transition and use it everywhere instead of
`lookupOrDefault`. This avoids mixed usage of the two methods that
are identical in behaviour, makes for shorter names, and promotes
the distinction between "lookup" access (ie, return a token stream,
locate and return an entry) and "get" access (ie, the above with
conversion to concrete types such as scalar, label etc).
- adds into the include-quoted search list instead the general (-Idir)
search list.
* makes it less subject to ordering (since it will now generally be
searched first) and makes it less subject to how duplicate removal
is implemented. In some compilers (#1627), the last instance of
a duplicate directory would be used and not the first instance.
* removes clutter in some Make/options files
COMP: add missing linkage libraries
Integration of VOF MULES new interfaces. Update of VOF solvers and all instances

Integration of reactingTwoPhaseEuler and reactingMultiphaseEuler solvers and sub-models
Updating reactingEuler tutorials accordingly (most of them tested)
New eRefConst thermo used in tutorials. Some modifications at thermo specie level
affecting mostly eThermo. hThermo mostly unaffected
New chtMultiRegionTwoPhaseEulerFoam solver for quenching and tutorial.
Phases sub-models for reactingTwoPhaseEuler and reactingMultiphaseEuler were moved

- Eg, with surface writers now in surfMesh, there are fewer libraries
depending on conversion and sampling.
COMP: regularize linkage ordering and avoid some implicit linkage (#1238)
- Global functions are unary or combining binary functions, which are
defined in MinMax.H (MinMaxOps.H).
There are also global reduction functions (gMinMax, gMinMaxMag)
as well as supporting 'Op' classes:
- minMaxOp, minMaxEqOp, minMaxMagOp, minMaxMagEqOp
Since the result of the functions represents a content reduction
into a single MinMax<T> value (a min/max pair), field operations
returning a field simply do not make sense.
- Implemented for lists, fields, field-fields, DimensionedField,
GeometricField (parallel reducing, with boundaries).
- Since the minMax evaluates during its operation, this makes it more
efficient for cases where both min/max values are required since it
avoids looping twice through the data.
* Changed GeometricField writeMinMax accordingly.
ENH: clip as field function
- clipping provides a more efficient, single-pass operation to apply
lower/upper limits on single or multiple values.
Examples,
scalarMinMax limiter(0, 1);
limiter.clip(value)
-> returns a const-ref to the value if within the range, or else
returns the appropriate lower/upper limit
limiter.inplaceClip(value)
-> Modifies the value if necessary to be within lower/upper limit
Function calls
clip(value, limiter)
-> returns a copy after applying lower/upper limit
clip(values, limiter)
-> returns a tmp<Field> of clipped values
- provide a lookupOrDefault constructor form, since this is a fairly
commonly used requirement and simplifies the calling sequence.
Before
dimensionedScalar rhoMax
(
dimensionedScalar::lookupOrDefault
(
"rhoMax",
pimple.dict(),
dimDensity,
GREAT
)
);
After
dimensionedScalar rhoMax("rhoMax", dimDensity, GREAT, pimple.dict());
- read, readIfPresent methods with alternative lookup names.
- Mark the Istream related constructors with compile-time deprecated
warnings.
BUG: read, readIfPresent methods not handling optional dimensions (#1148)
- makes the intent clearer and avoids the need for additional
constructor casting. Eg,
labelList(10, Zero) vs. labelList(10, 0)
scalarField(10, Zero) vs. scalarField(10, scalar(0))
vectorField(10, Zero) vs. vectorField(10, vector::zero)
- for some special cases we wish to mark command-line arguments as
being optional, in order to do our own treatment. For example,
when an arbitrary number of arguments should be allowed.
Now tag this situation with argList::noMandatoryArgs().
The argList::argsMandatory() query can then be used in any further
logic, including the standard default argument checking.
- with the new default check, can consolidate the special-purpose
"setRootCaseNonMandatoryArgs.H"
into the regular
"setRootCase.H"
- revert to a simple "setRootCase.H" and move all the listing related
bits to a "setRootCaseLists.H" file. This leaves the information
available for solvers, or whoever else wishes, without being
introduced everywhere.
- add include guards and scoping to the listing files and rename to
something less generic.
listOptions.H -> setRootCaseListOptions.H
listOutput.H -> setRootCaseListOutput.H
Previously the coordinate system functionality was split between
coordinateSystem and coordinateRotation. The coordinateRotation stored
the rotation tensor and handled all tensor transformations.
The functionality has now been revised and consolidated into the
coordinateSystem classes. The sole purpose of coordinateRotation
is now just to provide a selectable mechanism of how to define the
rotation tensor (eg, axis-angle, euler angles, local axes) for user
input, but after providing the appropriate rotation tensor it has
no further influence on the transformations.
--
The coordinateSystem class now contains an origin and a base rotation
tensor directly and various transformation methods.
- The origin represents the "shift" for a local coordinate system.
- The base rotation tensor represents the "tilt" or orientation
of the local coordinate system in general (eg, for mapping
positions), but may require position-dependent tensors when
transforming vectors and tensors.
For some coordinate systems (currently the cylindrical coordinate system),
the rotation tensor required for rotating a vector or tensor is
position-dependent.
The new coordinateSystem and its derivates (cartesian, cylindrical,
indirect) now provide a uniform() method to define if the rotation
tensor is position dependent/independent.
The coordinateSystem transform and invTransform methods are now
available in two-parameter forms for obtaining position-dependent
rotation tensors. Eg,
... = cs.transform(globalPt, someVector);
In some cases it can be useful to use query uniform() to avoid
storage of redundant values.
if (cs.uniform())
{
vector xx = cs.transform(someVector);
}
else
{
List<vector> xx = cs.transform(manyPoints, someVector);
}
Support transform/invTransform for common data types:
(scalar, vector, sphericalTensor, symmTensor, tensor).
====================
Breaking Changes
====================
- These changes to coordinate systems and rotations may represent
a breaking change for existing user coding.
- Relocating the rotation tensor into coordinateSystem itself means
that the coordinate system 'R()' method now returns the rotation
directly instead of the coordinateRotation. The method name 'R()'
was chosen for consistency with other low-level entities (eg,
quaternion).
The following changes will be needed in coding:
Old: tensor rot = cs.R().R();
New: tensor rot = cs.R();
Old: cs.R().transform(...);
New: cs.transform(...);
Accessing the runTime selectable coordinateRotation
has moved to the rotation() method:
Old: Info<< "Rotation input: " << cs.R() << nl;
New: Info<< "Rotation input: " << cs.rotation() << nl;
- Naming consistency changes may also cause code to break.
Old: transformVector()
New: transformPrincipal()
The old method name transformTensor() now simply becomes transform().
====================
New methods
====================
For operations requiring caching of the coordinate rotations, the
'R()' method can be used with multiple input points:
tensorField rots(cs.R(somePoints));
and later
Foam::transformList(rots, someVectors);
The rotation() method can also be used to change the rotation tensor
via a new coordinateRotation definition (issue #879).
The new methods transformPoint/invTransformPoint provide
transformations with an origin offset using Cartesian for both local
and global points. These can be used to determine the local position
based on the origin/rotation without interpreting it as a r-theta-z
value, for example.
================
Input format
================
- Streamline dictionary input requirements
* The default type is cartesian.
* The default rotation type is the commonly used axes rotation
specification (with e1/e2/3), which is assumed if the 'rotation'
sub-dictionary does not exist.
Example,
Compact specification:
coordinateSystem
{
origin (0 0 0);
e2 (0 1 0);
e3 (0.5 0 0.866025);
}
Full specification (also accepts the longer 'coordinateRotation'
sub-dictionary name):
coordinateSystem
{
type cartesian;
origin (0 0 0);
rotation
{
type axes;
e2 (0 1 0);
e3 (0.5 0 0.866025);
}
}
This simplifies the input for many cases.
- Additional rotation specification 'none' (an identity rotation):
coordinateSystem
{
origin (0 0 0);
rotation { type none; }
}
- Additional rotation specification 'axisAngle', which is similar
to the -rotate-angle option for transforming points (issue #660).
For some cases this can be more intuitive.
For example,
rotation
{
type axisAngle;
axis (0 1 0);
angle 30;
}
vs.
rotation
{
type axes;
e2 (0 1 0);
e3 (0.5 0 0.866025);
}
- shorter names (or older longer names) for the coordinate rotation
specification.

Coding Style
================
- use Foam::coordSystem namespace for categories of coordinate systems
(cartesian, cylindrical, indirect). This reduces potential name
clashes and makes a clearer declaration. Eg,
coordSystem::cartesian csys_;
The older names (eg, cartesianCS, etc) remain available via typedefs.
- added coordinateRotations namespace for better organization and
reduce potential name clashes.
- relocate some standard functionality to TimePaths to allow a lighter
means of managing time directories without using the entire Time
mechanism.
- optional enableLibs for Time construction (default is on)
and a corresponding argList::noLibs() and "-no-libs" option
STYLE:
- mark Time::outputTime() as deprecated MAY-2016
- use pre-increment for runTime, although there is no difference in
behaviour or performance.
chtMultiRegionFoam now supports reaction/combustion modelling in fluid
regions in the same way as reactingFoam.

To unsure fvOptions are instantiated for post-processing createFvOptions.H must

BUG: solvers: Moved fvOption construction into createFields.H for post-processing
This ensures that the fvOptions are constructed for the -postProcessing option
so that functionObjects which process fvOption data operate correctly in this
mode.
- controlled by the the 'printExecutionFormat' InfoSwitch in
etc/controlDict
// Style for "ExecutionTime = " output
// - 0 = seconds (with trailing 's')
// - 1 = day-hh:mm:ss
ExecutionTime = 112135.2 s ClockTime = 113017 s
ExecutionTime = 1-07:08:55.20 ClockTime = 1-07:23:37
- Callable via the new Time::printExecutionTime() method,
which also helps to reduce clutter in the applications.
Eg,
runTime.printExecutionTime(Info);
vs
Info<< "ExecutionTime = " << runTime.elapsedCpuTime() << " s"
<< " ClockTime = " << runTime.elapsedClockTime() << " s"
<< nl << endl;
--
ENH: return elapsedClockTime() and clockTimeIncrement as double
- previously returned as time_t, which is less portable.
- when constructing dimensioned fields that are to be zero-initialized,
it is preferrable to use a form such as
dimensionedScalar(dims, Zero)
dimensionedVector(dims, Zero)
rather than
dimensionedScalar("0", dims, 0)
dimensionedVector("zero", dims, vector::zero)
This reduces clutter and also avoids any suggestion that the name of
the dimensioned quantity has any influence on the field's name.
An even shorter version is possible. Eg,
dimensionedScalar(dims)
but reduces the clarity of meaning.
- NB: UniformDimensionedField is an exception to these style changes
since it does use the name of the dimensioned type (instead of the
regIOobject).
This is important when LTS stepping or large Co number is used.
