- can be used as a more natural test on the iterator.
For example, with
HashTable<..> table;
auto iter = table.find(...);
Following are now all equivalent:
1. if (iter != table.end()) ...
2. if (iter.found()) ...
3. if (iter) ...
- similar to autoPtr and unique_ptr. Returns the pointer value without
any checks. This provides a simple way for use to use either
an autoPtr or a tmp for local memory management without accidentally
stealing the pointer.
Eg,
volVectorField* ptr;
tmp<volVectorField> tempField;
if (someField.valid())
{
ptr = someField.get();
}
else
{
tempField.reset(new volVectorField(....));
ptr = tmpField.get();
}
const volVectorField& withField = *ptr;
STYLE: make more tmp methods noexcept
Averages columns of cells for layered meshes.
For each patch face, calculates the average value of all cells attached in
the patch face normal direction, and then pushes the average value back
to all cells in the column.
Useful for channel-like cases where we want to average fields in the
spanwise direction.
Example of function object specification:
columnAverage1
{
type columnAverage;
libs ("libfieldFunctionObjects.so");
...
patches (front side);
fields (U p);
}
Where the entries comprise:
\table
Property | Description | Required | Default value
type | type name: fieldMinMax | yes |
patches | list of patches to collapse onto | yes |
fields | list of fields to process | yes |
\endtable
- this corresponds to 'never match', which may be useful in combination
with -constant selection.
Eg,
surfaceMeshTriangulate -constant -time none
selects only the constant entry and suppresses any automatic time loop
STYLE: adjust help for the standard -times option
- indicate that times can be comma or space separated, since this is
otherwise not apparent. Don't mention semicolon separators in the help
since that just adds even more clutter.
- support .vtp format for geometry, surface, line, cloud.
- use native reader for handling vtk, vtp, obj, stl surface files.
For other formats, use the MeshedSurface (the surfMesh lib) to
handle reading and Foam::vtk::Tools::Patch to handle the
conversion to vtkPolyData. This combination is more memory efficient.
- update tutorial case to include vtp surface geometry
- for quantities such as face area/normals etc, it can be useful to
calculate directly and avoid the overhead of caching all the values.
STYLE: comments, use HashTable lookup() method in whichPoint()
- this allows more use of the runTimePostProcessing functionObject
that will fail more gracefully if the proper version could not be
built.
The dummy functionObject simply emits a message that it is not available.
- this is identical to either of these solutions:
* getEnv("FOAM_CASE")
* stringOps::expand("<case>")
but with a closer resemblance to argList or Time globalPath(),
which makes the intent clearer.
Avoids using raw strings in the caller, which improves compile-time checks.
Used in situations where a class has no derivation path or other
access to a time registry or command args.
- provide relativePath() for argList and for Time.
These are relative to the case globalPath().
Eg,
Info<< "output: " << runTime.relativePath(outputFile) << nl;
- partial solution for issue #1091
This generates file properties that are case-relative,
Eg,
plane0
{
p
{
file "<case>/postProcessing/plane0/1/p_plane0.vtk";
}
U
{
file "<case>/postProcessing/plane0/1/U_plane0.vtk";
}
}
This allows the case to be moved elsewhere and still find its files.
This functionality was previously added for vtkCloud, but now also
applies to streamLine, sampledSets and sampledSurfaces
- it is sufficient to provide the total number of times that findBinary()
failed instead of flooding the screen with messages
Full verbose warnings still emitted when debugging is on.
- 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)
- now use findEtcEntry() instead to handle file or directory.
Added findEtcEntries(), which provides provides a common code basis
for findEtcDirs(), findEtcFiles() ...
- this simplifies use of a unified test for directory or file.
fileName::Type what = myfile.type(true, true);
if (what == FILE) ...
if (what == DIRECTORY) ...
- Use distinct bit values for fileName::Type, for possible use in
the future.
- related to issue #1121, since we need a more flexible way of
expanding file or directory.
An alternative would be to add checkGzip to Foam::exists() and
Foam::type() functions, but that would make the code there more
confusing and in the fileHandler classes.
- 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
- Now also responds to the contents of the trigger file,
processing action= contents similar to used with external coupling.
Previously it only handled an action that was defined in the
dictionary. With this update, the user can chose a diferent action
simply by echoing the appropriate action string into the trigger
file.
- similar to the foamEtcFile script -mode=... option, the specific
search location (user/group/other) can now also specified for
string expansions and as a numerical value for etcFile()
For example, if searching for group or other (project) controlDict,
but not wishing to see the user controlDict:
1. foamEtcFile -mode=go controlDict
2. fileName dictFile("<etc:go>/controlDict");
dictFile.expand();
3. etcFile(controlDict, false, 0077);
The default behaviour for searching all contexts is unchanged.
1. foamEtcFile controlDict
2. fileName dictFile("<etc>/controlDict");
dictFile.expand();
3. etcFile(controlDict);
- the local third-party headers are to be searched before any MPI
include directories. This stops the situation where an mpi-specific
version of ptscotch.h is installed into the MPI directories.
This "system" version may well have a different SCOTCH_Num size
(32 bit vs 64 bit) from the third-party library etc.
