- flowRate: volume flow-rate through given patches
- flowRatePartition: distribution of the inlet flow-rate to certain
outlet patches, with given percentages
- uniformityPatch: uniformity of the velocity field at given (outlet) patches,
expressed as (half) the variance of the velocity field
- uniformityCellZone: same as uniformityPatch, but defined over
cellZones
- powerDissipation: the fluid power dissipation taking place within
given cellZones. In the absence of viscous stress at the "inlets" and
"outlets" of the cellZones, this corresponds to the volume flow-rate
weighted total pressure losses through the cellZones
ENH: updated nutSqr so it can be used with adjointkOmegaSST too
to help allocate pointers related to contributions to the adjoint
turbulence model PDEs, populate them and check the validity of the
cellZones provided for cellZone-based objectives
This pack adds a new entry 'parcelTypes' which can specify the list of
parcel type IDs interacting with a surface film. If the entry
is omitted, all particle types are considered.
```
surfaceFilmModel kinematicSurfaceFilm;
kinematicSurfaceFilmCoeffs
{
interactionType absorb;
// Optional list of participating parcel IDs
parcelTypes (10);
}
```
To set the parcel type by injector, 'injectorID' entry can be used
when specifying the injector models, e.g.
```
injectionModels
{
model1
{
type <injectionModelType>;
// Optional injector ID
// - if ommitted, parcels use '-1'
injectorID 10;
...
}
}
```
- make fileHandler deletion mechanism more
transparent by providing a nullptr signature. A nullptr parameter
is already being used in the argList destructor for shutdown, but that
relied on an implicit conversion to autoPtr to trigger things.
- improved handling of file handler replacement.
Previously had a very basic check on old vs new handlers using their
type() values (string comparison!!), which would unfortunately
prevent proper swapping of the contents.
Check the actual pointers instead.
As part of the change, treat any empty autoPtr as no-op instead of as
deletion (which is handled explicitly as nullptr instead).
In addition to making the internal logic simpler, it means that the
current file handler always changes to a valid state without
inadvertently removing everything and falling back to creating a new
default handler (again).
This handling of no-ops also simplifies call code. For example,
<code>
autoPtr<fileHandler> oldHandler;
autoPtr<fileHandler> writeHandler;
word handlerName;
if (arg.readIfPresent("writeHandler", handlerName))
{
writeHandler = fileOperation::New(handlerName);
}
oldHandler = fileHandler(std::move(writeHandler));
... do something
writeHandler = fileHandler(std::move(oldHandler));
</code>
If the "writeHandler" is not specified, each call is a no-op.
If it is specified, the handlers are swapped out each time.
- the management of the fileHandler communicators is now encapsulated
privately (managedComm_) with the final layer being responsible for
cleaning up after itself. This makes delegation/inheritance clearer
and avoids the risk of freeing an MPI communicator twice.
STYLE: uniformFile static check relocated to fileOperation layer
- UPstream::globalComm constant always refers to MPI_COMM_WORLD but
UPstream::worldComm could be MPI_COMM_WORLD (single world)
or a dedicated local communicator (for multi-world).
- provide a Pstream wrapped version of MPI_COMM_SELF,
references as UPstream::selfComm
- UPstream::isUserComm(label)
test for additional user-defined communicators
- recover the target of symbolic links.
This is needed when re-creating a file tree on another rank.
ENH: handle checkGzip, followLink flags in fileHander filePath()
- previously just relied on the backend defaults, now pass through
- separate init(...) for common constructor init steps
- was previously populated with "IOobject" (the typeName) but then
cannot easily detect if the object was actually read.
Also clear the headerClassName on a failed read
BUG: parallel inconsistency in regIOobject::readHeaderOk
- headerOk() checked with master, but possible parallel operations
within it
- comprises a few different elements:
FilterField (currently packaged in PatchFunction1Types namespace)
~~~~~~~~~~~
The FilterField helper class provides a multi-sweep median filter
for a Field of data associated with a geometric point cloud.
The points can be freestanding or the faceCentres (or points)
of a meshedSurface, for example.
Using an initial specified search radius, the nearest point
neighbours are gathered and addressing/weights are built for them.
This currently uses an area-weighted, linear RBF interpolator
with provision for quadratic RBF interpolator etc.
After the weights and addressing are established,
the evaluate() method can be called to apply a median filter
to data fields, with a specified number of sweeps.
boundaryDataSurfaceReader
~~~~~~~~~~~~~~~~~~~~~~~~~
- a surfaceReader (similar to ensightSurfaceReader) when a general
point data reader is needed.
MappedFile
~~~~~~~~~~
- has been extended to support alternative surface reading formats.
This allows, for example, sampled ensight data to be reused for
mapping. Cavaet: multi-patch entries may still needs some work.
- additional multi-sweep median filtering of the input data.
This can be used to remove higher spatial frequencies when
sampling onto a coarse mesh.
smoothSurfaceData
~~~~~~~~~~~~~~~~~
- standalone application for testing of filter radii/sweeps
Changes / Improvements
- more consistent subsetting, interface
* Extend the use of subset and non-subset collections with uniform
internal getters to ensure that the subset/non-subset versions
are robustly handled.
* operator[](label) and objectIndex(label) for standardized access
to the underlying item, or the original index, regardless of
subsetting or not.
* centres() and centre(label) for representative point cloud
information.
* nDim() returns the object dimensionality (0: point, 1: line, etc)
these can be used to determine how 'fat' each shape may be
and whether bounds(labelList) may contribute any useful information.
* bounds(labelList) to return the full bound box required for
specific items. Eg, the overall bounds for various 3D cells.
- easier construction of non-caching versions. The bounding boxes are
rarely cached, so simpler constructors without the caching bool
are provided.
- expose findNearest (bound sphere) method to allow general use
since this does not actually need a tree.
- static helpers
The boxes() static methods can be used by callers that need to build
their own treeBoundBoxList of common shapes (edge, face, cell)
that are also available as treeData types.
The bounds() static methods can be used by callers to determine the
overall bound-box size prior to constructing an indexedOctree
without writing ad hoc code inplace.
Not implemented for treeDataPrimitivePatch since similiar
functionality is available directly from the PrimitivePatch::box()
method with less typing.
========
BREAKING: cellLabels(), faceLabels(), edgeLabel() access methods
- it was always unsafe to use the treeData xxxLabels() methods without
subsetting elements. However, since the various classes
(treeDataCell, treeDataEdge, etc) automatically provided
an identity lookup, this problem was not apparent.
Use objectIndex(label) to safely de-reference to the original index
and operator[](index) to de-reference to the original object.
