- The writers have changed from being a generic state-less set of
routines to more properly conforming to the normal notion of a writer.
These changes allow us to combine output fields (eg, in a single
VTK/vtp file for each timestep).
Parallel data reduction and any associated bookkeeping is now part
of the surface writers.
This improves their re-usability and avoids unnecessary
and premature data reduction at the sampling stage.
It is now possible to have different output formats on a per-surface
basis.
- A new feature of the surface sampling is the ability to "store" the
sampled surfaces and fields onto a registry for reuse by other
function objects.
Additionally, the "store" can be triggered at the execution phase
as well
- the utility had automatic triangulation removed some time ago, but
never changed its name.
- catch old uses with a surfaceMeshTriangulate deprecated script
- 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)
- note that it does not actually triangulate unless necessary, should
probably receive a new name.
- use newer constructs for handling processor/non-processor patch
selection etc.
- provide relativePath() for argList and for Time.
These are relative to the case globalPath().
Eg,
Info<< "output: " << runTime.relativePath(outputFile) << nl;
- as part of the cleanup of dictionary access methods (c6520033c9)
made the dictionary class single inheritance from IDLList<entry>.
This eliminates any ambiguities for iterators and allows
for simple use of range-for looping.
Eg,
for (const entry& e : topDict))
{
Info<< "entry:" << e.keyword() << " is dict:" << e.isDict() << nl;
}
vs
forAllConstIter(dictionary, topDict, iter))
{
Info<< "entry:" << iter().keyword()
<< " is dict:" << iter().isDict() << nl;
}
- instead of dict.lookup(name) >> val;
can use dict.readEntry(name, val);
for checking of input token sizes.
This helps catch certain types of input errors:
{
key1 ; // <- Missing value
key2 1234 // <- Missing ';' terminator
key3 val;
}
STYLE: readIfPresent() instead of 'if found ...' in a few more places.
- With argList::noFunctionObjects() we use the logic added in
4b93333292 (issue #352)
By removing the '-noFunctionObjects' option, we automatically
suppress the creation of function-objects via Time (with argList
as a parameter).
There is generally no need in these cases for an additional
runTime.functionObjects().off() statement
Use the argList::noFunctionObjects() for more direct configuration
and reduce unnecessary clutter in the -help information.
In previous versions, the -noFunctionObjects would have been redundant
anyhow, so we can also just ignore it now instead.
- signedDistance() method is like distance() but retains
the positive/negative sign for the side of the plane.
- the sign() method returns the sign as -1,0,+1 integer for
classification purposes where it is important to distinguish between
a zero value and a positive value (eg, for cutting). Optional
tolerance can be supplied to round for zero.
- refactor and inlined simple and frequently used methods.
- add boundBox faceCentre() method, which can be useful for creating
clipping planes from a bounding box.
Relocated treeBoundBox faceNormals to boundBox since they apply
equally there - the meaning of the faces (x-min, x-max, etc)
is the same, even if the point addressing for the faces differs.
- 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
- add additional control via a Foam::infoDetailLevel flag, which is
supported by a 'DetailLevel' macro. Eg,
DetailLevel << "some information" << nl
- When infoDetailLevel is zero, the stdout for all Foam::system() calls
are also redirected to stderr to prevent child output from
appearing on the parent.
- close stdin before exec in system call.
- 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.
- 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.
- Since 'bool' and 'Switch' use the _identical_ input mechanism
(ie, both accept true/false, on/off, yes/no, none, 1/0), the main
reason to prefer one or the other is the output.
The output for Switch is as text (eg, "true"), whereas for bool
it is label (0 or 1). If the output is required for a dictionary,
Switch may be appropriate. If the output is not required, or is only
used for Pstream exchange, bool can be more appropriate.
