- rationalized code dealing with extraction of name or indices from
coordinateSystems, polyBoundaryMesh, faBoundaryMesh, fvBoundaryMesh,
ZoneMesh to use internal implementations that allow direct
searching/matching without building an intermediate list of names.
- simpler and more efficient handling of patch group matching.
- centralizes IOobject handling and treatment of alternative locations.
If an alternative file location is specified, it will be used instead.
- provide decompositionMethod::canonicalName instead of using
"decomposeParDict" in various places.
General:
* -roots, -hostRoots, -fileHandler
Specific:
* -to <coordinateSystem> -from <coordinateSystem>
- Display -help-compat when compatibility or ignored options are available
STYLE: capitalization of options text
- avoids compiler ambiguity when virtual methods such as
IOdictionary::read() exist.
- the method was introduced in 1806, and was thus not yet widely used
- simplifies usage.
Support syncPar check on names() to detect inconsistencies.
- simplify readFields, ReadFields and other routines by using these
new methods.
- aids with detection of excess tokens (issue #762)
- deprecated dictionary::operator[] in favour of the lookup() method
which offers more flexibilty and clarity of purpose.
Additionally, the read<> and get<> forms should generally be used
instead anyhow.
- improves backward compatibility and more naming consistency.
Retain setMany(iter1, iter2) to avoid ambiguity with the
PackedList::set(index, value) method.
- The iterator for a HashSet dereferences directly to its key.
- Eg,
for (const label patchi : patchSet)
{
...
}
vs.
forAllConstIter(labelHashSet, patchSet, iter)
{
const label patchi = iter.key();
...
}
- 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.
- generalize some of the library extensions (.so vs .dylib).
Provide as wmake 'sysFunctions'
- added note about unsupported/incomplete system support
- centralize detection of ThirdParty packages into wmake/ subdirectory
by providing a series of scripts in the spirit of GNU autoconfig.
For example,
have_boost, have_readline, have_scotch, ...
Each of the `have_<package>` scripts will generally provide the
following type of functions:
have_<package> # detection
no_<package> # reset
echo_<package> # echoing
and the following type of variables:
HAVE_<package> # unset or 'true'
<package>_ARCH_PATH # root for <package>
<package>_INC_DIR # include directory for <package>
<package>_LIB_DIR # library directory for <package>
This simplifies the calling scripts:
if have_metis
then
wmake metisDecomp
fi
As well as reducing clutter in the corresponding Make/options:
EXE_INC = \
-I$(METIS_INC_DIR) \
-I../decompositionMethods/lnInclude
LIB_LIBS = \
-L$(METIS_LIB_DIR) -lmetis
Any additional modifications (platform-specific or for an external build
system) can now be made centrally.
- IOstreamOption class to encapsulate format, compression, version.
This is ordered to avoid internal padding in the structure, which
reduces several bytes of memory overhead for stream objects
and other things using this combination of data.
Byte-sizes:
old IOstream:48 PstreamBuffers:88 Time:928
new IOstream:24 PstreamBuffers:72 Time:904
====
STYLE: remove support for deprecated uncompressed/compressed selectors
In older versions, the system/controlDict used these types of
specifications:
writeCompression uncompressed;
writeCompression compressed;
As of DEC-2009, these were deprecated in favour of using normal switch
names:
writeCompression true;
writeCompression false;
writeCompression on;
writeCompression off;
Now removed these deprecated names and treat like any other unknown
input and issue a warning. Eg,
Unknown compression specifier 'compressed', assuming no compression
====
STYLE: provide Enum of stream format names (ascii, binary)
====
COMP: fixed incorrect IFstream construct in FIREMeshReader
- spurious bool argument (presumably meant as uncompressed) was being
implicitly converted to a versionNumber. Now caught by making
IOstreamOption::versionNumber constructor explicit.
- bad version specifier in changeDictionary
- the expansions were previously required as slash to follow, but
now either are possible.
"<case>", "<case>/" both yield the same as "$FOAM_CASE" and
will not have a trailing slash in the result. The expansion of
"$FOAM_CASE/" will however have a trailing slash.
- adjust additional files using these expansions
- 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).
- in many cases can just use lookupOrDefault("key", bool) instead of
lookupOrDefault<bool> or lookupOrDefault<Switch> since reading a
bool from an Istream uses the Switch(Istream&) anyhow
STYLE: relocated Switch string names into file-local scope
This class is largely a pre-C++11 holdover. It is now possible to
simply use move construct/assignment directly.
In a few rare cases (eg, polyMesh::resetPrimitives) it has been
replaced by an autoPtr.
* For most cases, this conversion would be largely unintentional
and also less efficient. If the regex is desirable, the caller
should invoke it explicitly.
For example,
findStrings(regExp(str), listOfStrings);
Or use one of the keyType, wordRe, wordRes variants instead.
If string is to be used as a plain (non-regex) matcher,
this can be directly invoked
findMatchingStrings(str, listOfStrings);
or using the ListOps instead:
findIndices(listOfStrings, str);
* provide function interfaces for keyType.
- use succincter method names that more closely resemble dictionary
and HashTable method names. This improves method name consistency
between classes and also requires less typing effort:
args.found(optName) vs. args.optionFound(optName)
args.readIfPresent(..) vs. args.optionReadIfPresent(..)
...
args.opt<scalar>(optName) vs. args.optionRead<scalar>(optName)
args.read<scalar>(index) vs. args.argRead<scalar>(index)
- the older method names forms have been retained for code compatibility,
but are now deprecated
Within decomposeParDict, it is now possible to specify a different
decomposition method, methods coefficients or number of subdomains
for each region individually.
The top-level numberOfSubdomains remains mandatory, since this
specifies the number of domains for the entire simulation.
The individual regions may use the same number or fewer domains.
Any optional method coefficients can be specified in a general
"coeffs" entry or a method-specific one, eg "metisCoeffs".
For multiLevel, only the method-specific "multiLevelCoeffs" dictionary
is used, and is also mandatory.
----
ENH: shortcut specification for multiLevel.
In addition to the longer dictionary form, it is also possible to
use a shorter notation for multiLevel decomposition when the same
decomposition method applies to each level.
old "positions" file form
The change to barycentric-based tracking changed the contents of the
cloud "positions" file to a new format comprising the barycentric
co-ordinates and other cell position-based info. This broke
backwards compatibility, providing no option to restart old cases
(v1706 and earlier), and caused difficulties for dependent code, e.g.
for post-processing utilities that could only infer the contents only
after reading.
The barycentric position info is now written to a file called
"coordinates" with provision to restart old cases for which only the
"positions" file is available. Related utilities, e.g. for parallel
running and data conversion have been updated to be able to support both
file types.
To write the "positions" file by default, use set the following option
in the InfoSwitches section of the controlDict:
writeLagrangianPositions 1;
Tracking data classes are no longer templated on the derived cloud type.
The advantage of this is that they can now be passed to sub models. This
should allow continuous phase data to be removed from the parcel
classes. The disadvantage is that every function which once took a
templated TrackData argument now needs an additional TrackCloudType
argument in order to perform the necessary down-casting.
