- 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.
- more memory efficient within loops
- octree/boundBox overlaps().
Like findBox(), findSphere() but early exit if any shapes overlap.
ENH: additional query for nLeafs()
- don't need separate scratch arrays (avoids possible reallocations
when split is imbalanced)
ENH: upgrade dynamicIndexedOctree to use DynamicList directly
- with C++11 move semantics don't need lists of autoPtr
for efficient transfers
- use default initialize boundBox instead of invertedBox
- reset() instead of assigning from invertedBox
- extend (three parameter version) and grow method
- inflate(Random) instead of extend + re-assigning
- null() static method
* as const reference to the invertedBox with the appropriate casting.
- boundBox inflate(random)
* refactored from treeBoundBox::extend, but allows in-place modification
- boundBox::hexFaces() instead of boundBox::faces
* rarely used, but avoids confusion with treeBoundBox::faces
and reuses hexCell face definitions without code duplication
- boundBox::hexCorners() for corner points corresponding to a hexCell.
Can also be accessed from a treeBoundBox without ambiguity with
points(), which could be hex corners (boundBox) or octant corners
(treeBoundBox)
- boundBox::add with pairs of points
* convenient (for example) when adding edges or a 'box' that has
been extracted from a primitive mesh shape.
- declare boundBox nPoints(), nFaces(), nEdges() as per hexCell
ENH: return invertedBox instead of FatalError for empty trees
- similar to #2612
ENH: cellShape(HEX, ...) + boundBox hexCorners for block meshes
STYLE: cellModel::ref(...) instead of de-reference cellModel::ptr(...)
- the boundBox for a given cell, using the cheapest calculation:
- cellPoints if already available, since this will involve the
fewest number of min/max comparisions.
- otherwise walk the cell faces: via the cell box() method
to avoid creating demand-driven cellPoints etc.
ENH: use direct access to pointHit as point(), use dist(), distSqr()
- if the pointHit has already been checked for hit(), can/should
simply use point() noexcept access subsequently to avoid redundant
checks. Using vector distSqr() methods provides a minor optimization
(no itermediate temporary), but can also make for clearer code.
ENH: copy construct pointIndexHit with different index
- symmetric with constructing from a pointHit with an index
STYLE: prefer pointHit point() instead of rawPoint()
ENH: use DynamicList instead of List + size for point wave
- consistent with previous updates for the other algorithms
STYLE: unique_ptr instead of raw pointer in wave algorithms
- provides fast compile-time indexing for FixedList
(invalid indices trigger a compiler error).
This enables noexcept access, which can propagate into various
other uses (eg, triFace, triPoints, ...)
ENH: add triangle edge vectors
- traditionally used first(), last() methods,
but front(), back() are well-known from std::vector etc
which makes the access more familiar.
- support push_back() method for containers that already had append().
This increases name familiar and can help when porting between
different C++ code bases.
- support pop_back() method for List containers.
This is similar to std::vector
- ie, front(), back(), push_front(), push_back(), pop_front()
ENH: add CircularBuffer flattening operator() and list() method
- useful if assigning content to a List etc
BUG: CircularBuffer find() did not return logical index
Grid independency studies and grid adaptation for implicit LES/DES are
nontrivial and intractable due to the inherent coupling between spatial
resolution and subgrid-scale modelling.
To enable assessments for LES/DES resolution, a function object of
single-mesh resolution index with three submodels is introduced.
- replaced PstreamBuffers mechanism with globalIndex for both gather
and scatter operations. Use scheduled communication by default, but
is selectable.
- reduced communication with ensemble averaging and no-write
- pattern as per surfaceFieldValue::setFaceZoneFaces()
1. define faceId, facePatchId assuming an internal face
2. if actually a boundary face:
- get facePatchId
- ignore if emptyPolyPatch or coupledPolyPatch (neighbour side)
- get patch relative faceId
This currently seems to be the least amount of code clutter.
ENH: recover some memory my shrinking lists in fluxSummary
BUG: potentially trailing rubbish in the heatExchangerModel lists
- the final resize to length actually used was missing.
Does not affect any released versions
