- these are suitable for use with lambda functions.
- Deprecate the unused 3-parameter version of subset/inplaceSubset.
- Deprecate initList and initListList in favour of initializer_list
STYLE: adjust some comments, remove dead code in regionSizeDistribution.C
Description
Base-class for thermophysical properties of solids, liquids and gases
providing an interface compatible with the templated thermodynamics
packages.
liquidProperties, solidProperties and thermophysicalFunction libraries have been
combined with the new thermophysicalProperties class into a single
thermophysicalProperties library to simplify compilation and linkage of models,
libraries and applications dependent on these classes.
The fundamental properties provided by the specie class hierarchy were
mole-based, i.e. provide the properties per mole whereas the fundamental
properties provided by the liquidProperties and solidProperties classes are
mass-based, i.e. per unit mass. This inconsistency made it impossible to
instantiate the thermodynamics packages (rhoThermo, psiThermo) used by the FV
transport solvers on liquidProperties. In order to combine VoF with film and/or
Lagrangian models it is essential that the physical propertied of the three
representations of the liquid are consistent which means that it is necessary to
instantiate the thermodynamics packages on liquidProperties. This requires
either liquidProperties to be rewritten mole-based or the specie classes to be
rewritten mass-based. Given that most of OpenFOAM solvers operate
mass-based (solve for mass-fractions and provide mass-fractions to sub-models it
is more consistent and efficient if the low-level thermodynamics is also
mass-based.
This commit includes all of the changes necessary for all of the thermodynamics
in OpenFOAM to operate mass-based and supports the instantiation of
thermodynamics packages on liquidProperties.
Note that most users, developers and contributors to OpenFOAM will not notice
any difference in the operation of the code except that the confusing
nMoles 1;
entries in the thermophysicalProperties files are no longer needed or used and
have been removed in this commet. The only substantial change to the internals
is that species thermodynamics are now "mixed" with mass rather than mole
fractions. This is more convenient except for defining reaction equilibrium
thermodynamics for which the molar rather than mass composition is usually know.
The consequence of this can be seen in the adiabaticFlameT, equilibriumCO and
equilibriumFlameT utilities in which the species thermodynamics are
pre-multiplied by their molecular mass to effectively convert them to mole-basis
to simplify the definition of the reaction equilibrium thermodynamics, e.g. in
equilibriumCO
// Reactants (mole-based)
thermo FUEL(thermoData.subDict(fuelName)); FUEL *= FUEL.W();
// Oxidant (mole-based)
thermo O2(thermoData.subDict("O2")); O2 *= O2.W();
thermo N2(thermoData.subDict("N2")); N2 *= N2.W();
// Intermediates (mole-based)
thermo H2(thermoData.subDict("H2")); H2 *= H2.W();
// Products (mole-based)
thermo CO2(thermoData.subDict("CO2")); CO2 *= CO2.W();
thermo H2O(thermoData.subDict("H2O")); H2O *= H2O.W();
thermo CO(thermoData.subDict("CO")); CO *= CO.W();
// Product dissociation reactions
thermo CO2BreakUp
(
CO2 == CO + 0.5*O2
);
thermo H2OBreakUp
(
H2O == H2 + 0.5*O2
);

thermodynamic at https://bugs.openfoam.org

- Introduce writeList(Ostream&, label) method in various List classes to
provide more flexibility and avoid hard-coded limits when deciding if a
list is too long and should be broken up into multiple lines (ASCII only).
- The old hard-code limit (10) is retained in the operator<< versions
- This functionality is wrapped in the FlatOutput output adapter class
and directly accessible via the 'flatOutput()' function.
Eg,
#include "ListOps.H"
Info<< "methods: " << flatOutput(myLongList) << endl;
// OR
Info<< "methods: ";
myLongList.writeList(os) << endl;
- Constructs a validated word, in which all invalid characters have
been stripped out and any leading digit is '_'-prefixed.
Words with leading digits cause parse issues when read back later.
- Replaces previous functionally identical code from src/conversion
--
COMP: test against nullObject instead of checking address for null pointer.
- Constructor for bounding box of a single point.
- add(boundBox), add(point) ...
-> Extend box to enclose the second box or point(s).
Eg,
bb.add(pt);
vs.
bb.min() = Foam::min(bb.min(), pt);
bb.max() = Foam::max(bb.max(), pt);
Also works with other bounding boxes.
Eg,
bb.add(bb2);
// OR
bb += bb2;
vs.
bb.min() = Foam::min(bb.min(), bb2.min());
bb.max() = Foam::max(bb.max(), bb2.max());
'+=' operator allows the reduction to be used in parallel
gather/scatter operations.
A global '+' operator is not currently needed.
Note: may be useful in the future to have a 'clear()' method
that resets to a zero-sized (inverted) box.
STYLE: make many bounding box constructors explicit
reduce()
- parallel reduction of min/max values.
Reduces coding for the callers.
Eg,
bb.reduce();
instead of the previous method:
reduce(bb.min(), minOp<point>());
reduce(bb.max(), maxOp<point>());
STYLE:
- use initializer list for creating static content
- use point::min/point::max when defining standard boxes
- to the referenced object via a method name, which may be clearer
than deferencing the iterator
[key, value] => iter.key(), *iter
[key, value] => iter.key(), iter()
[key, value] => iter.key(), iter.object()
- makes it easier to use as a wordHashSet replacement for situations
where we want to avoid duplicates but retain the input order.
- support construction from HashTable, which means it works like the
HashTable::sortedToc but with its own hashing for these keys.
- expose rehash() method for the user. There is normally no need for
using it directly, but also no reason to lock it away as private.
e.g. in tutorials/heatTransfer/buoyantSimpleFoam/externalCoupledCavity/0/T
hot
{
type externalCoupledTemperature;
commsDir "${FOAM_CASE}/comms";
file "data";
initByExternal yes;
log true;
value uniform 307.75; // 34.6 degC
}
Previously both 'file' and 'fileName' were used inconsistently in different
classes and given that there is no confusion or ambiguity introduced by using
the simpler 'file' rather than 'fileName' this change simplifies the use and
maintenance of OpenFOAM.
- As the names describe, check if the string starts or ends with a
particular value. Always true if the given text is empty or if the
string is identical to the given text.
- add an extension to the file name
- remove a file extension
- check if a file name has an extension
- check if a file name has a particular extension (as word),
or matches a particular grouping of extensions (as wordRe).
This slightly more convenient when working with char[] input:
fileName file1{ "path", "name", "to", "file.ext" };
vs. fileName file1 = fileName(path)/"name"/"to"/"file.ext";
But is a bit more efficient since it avoid most of the intermediate
copying and resizing incurred by the '/' operator.
ENH: improve objectRegistry functionality (issue #322)
- Recursive searching for objects within a registry is now optional
(previous it was always done).
A recursive search effectively blocks the construction of sub-sub-registries
if their names are 'masked' by some parent level sub-registry with
the same name! (BUG)
- Recursive search is now turned OFF by default, which makes it consistent
with dictionary and probably causes the least number of surprises.
----
Various new convenience methods added:
lookupObjectRef()
- returns a non-const reference.
For example,
volScalarField& U = mesh().lookupObjectRef<volScalarField>("U");
Instead of
volScalarField& U = const_cast<volScalarField&>
(
mesh().lookupObject<volScalarField>("U")
);
--
lookupObjectPtr()
- returns a const pointer, and nullptr on failure.
For example,
const volScalarField* Uptr = mesh().lookupObjectPtr<volScalarField>("U");
if (Uptr)
{
const volScalarField& U = *Uptr;
...
}
Instead of
if (mesh().foundObject<volScalarField>("U"))
{
const volScalarField& U = mesh().lookupObject<volScalarField>("U");
...
}
--
lookupObjectRefPtr()
- returns a non-const pointer, and nullptr on failure.
For example,
volScalarField* Uptr = mesh().lookupObjectRefPtr<volScalarField>("U");
if (Uptr)
{
volScalarField& U = *Uptr; // use as reference
(*Uptr) = ...; // or use directly
}
Instead of
if (mesh().foundObject<volScalarField>("U"))
{
volScalarField& U = const_cast<volScalarField&>
(
mesh().lookupObject<volScalarField>("U")
);
}
--
sortedNames()
- now works with template parameters and with regular expression
matching as well.
For example,
wordList names = mesh().sortedNames();
wordList fields = mesh().sortedName<volScalarField>();
Instead of
wordList names = mesh().sortedNames();
wordList fields = mesh().names<volScalarField>();
Foam::sort(fields);

- The null constructor already creates a dimensionless Zero,
but named "undefined".
Provide an constructor for a dimensioned Zero,
but named "0" for universal clarity to its value.
- triFace() now initialized with '-1', which makes it behave
equivalently to face(label).
- supply default region=0 for some labelledTri constructors.
This allows labelledTri to work more like a triFace and makes it
easier to use in templated methods and eases conversion from
triFace to a labelledTri.
- labelledTri(const labelUList&) can now be used when converting
from a face. It can have 3 values (use default region)
or 4 values (with region).
- face, triFace, labelledTri now all support construction with
initializer lists. This can be useful for certain types of code.
Eg,
triFace f1{a, b, c};
face f2{a, b, c};
labelledTri f3{a, b, c};
Work without ambiguity.
Also useful for templated methods:
FaceType f{remap[a], remap[b], remap[c]};
- Cannot pass through to underlying list constructor directly.
- As this constructor was broken, there seem to be a number of
workarounds scattered in the code. Could revisit them in the future
as part of code-style:
edgeMesh(const Xfer<pointField>&, const Xfer<edgeList>&);
CompactIOField(const IOobject&, const Xfer<Field<T>>&);
GlobalIOField(const IOobject&, const Xfer<Field<Type>>&);
IOField(const IOobject&, const Xfer<Field<Type>>&);

By including "endian.H", either one of WM_BIG_ENDIAN or WM_LITTLE_ENDIAN
will be defined.
Provides inline 32-bit and 64-bit byte swap routines that can be
used/re-used elsewhere.
The inplace memory swaps currently used by the VTK output are left for
the moment pending further cleanup of that code.
