- additional distribute/reverseDistribute with specified commsType.
Improves flexibility.
- distribute with nullValue
- support move construct mapDistribute from mapDistributeBase
- refactor handling of schedules (as whichSchedule method) to
simplify code.
- renumberMap helper for working with compact sub maps
and renumberVisit for handling walk-ordered compaction.
COMP: make mapDistributeBase data private
- accessor methods are available - direct access is unnecessary
- mapDistribute : inherit mapDistributeBase constructors
STYLE: use List<labelPair>::null() for schedule placeholders
- clearer that they are doing nothing
- commonly used, only depends on routines defined in UList
(don't need the rest of ListOps for it).
ENH: implement boolList::operator() const
- allows use as a predicate functor, as per bitSet and labelHashSet
GIT: combine SubList, UList into List directory (intertwined concepts)
STYLE: default initialize DynamicList instead of with size 0
- direct construct and reset method for creating a zero-sized (dummy)
subMesh. Has no exposed faces and no parallel synchronization
required.
- core mapping (interpolate) functionality with direct handling
of subsetting in fvMeshSubset (src/finiteVolume).
Does not use dynamicMesh topology changes
- two-step subsetting as fvMeshSubsetter (src/dynamicMesh).
Does use dynamicMesh topology changes.
This is apparently only needed by the subsetMesh application itself.
DEFEATURE: remove deprecated setLargeCellSubset() method
- was deprecated JUL-2018, now removed (see issue #951)
- allows reuse by finiteArea, for example.
- simplify edge looping with face thisLabel/nextLabel method
ENH: additional storage checks for mesh weights (faMesh + fvMesh)
- allow finite-area field decomposition without edge weights.
STYLE: use tmp New in various places. Simpler updateGeom check
- was in fvMotionSolver, but only requires PatchFunction1 capabilities
(from within meshTools).
GIT: relocate IOmapDistributePolyMesh (from dynamicMesh to OpenFOAM)
- additional Pstream::broadcasts() method to serialize/deserialize
multiple items.
- revoke the broadcast specialisations for std::string and List(s) and
use a generic broadcasting template. In most cases, the previous
specialisations would have required two broadcasts:
(1) for the size
(2) for the contiguous content.
Now favour reduced communication over potential local (intermediate)
storage that would have only benefited a few select cases.
ENH: refine PstreamBuffers access methods
- replace 'bool hasRecvData(label)' with 'label recvDataCount(label)'
to recover the number of unconsumed receive bytes from specified
processor. Can use 'labelList recvDataCounts()' to recover the
number of unconsumed receive bytes from all processor.
- additional peekRecvData() method (for transcribing contiguous data)
ENH: globalIndex whichProcID - check for isLocal first
- reasonable to assume that local items are searched for more
frequently, so do preliminary check for isLocal before performing
a more costly binary search of globalIndex offsets
ENH: masterUncollatedFileOperation - bundled scatter of status
- use vector::removeCollinear a few places
COMP: incorrect initialization order in edgeFaceCirculator
COMP: Silence boost bind deprecation warnings (before CGAL-5.2.1)
- support direct processing of CompactListList instead of requiring
a conversion to labelListList for bandCompression and renumbering
methods.
- manage FIFO with CircularBuffer instead of SLList (avoids
allocations in inner loops). Invert logic to use a bitSet of
unvisited cells, which improves looping as the matrix becomes more
sparse.
- fix missed weighting in bandCompression (same as #1376).
In polyTopoChange, handle removed cells immediately to simplify
the logic and align more closely with bandCompression.
STYLE: enclose bandCompression within meshTools namespace
ENH: PrimitivePatch pointFaces with DynamicList instead of SLList
- bundles frequently used 'gather/scatter' patterns more consistently.
- combineAllGather -> combineGather + broadcast
- listCombineAllGather -> listCombineGather + broadcast
- mapCombineAllGather -> mapCombineGather + broadcast
- allGatherList -> gatherList + scatterList
- reduce -> gather + broadcast (ie, allreduce)
- The allGatherList currently wraps gatherList/scatterList, but may be
replaced with a different algorithm in the future.
STYLE: PstreamCombineReduceOps.H is mostly unneeded now
- when writing surface formats (eg, vtk, ensight etc) the sampled
surfaces merge the faces/points originating from different
processors into a single surface (ie, patch gatherAndMerge).
Previous versions of mergePoints simply merged all points possible,
which proves to be rather slow for larger meshes. This has now been
modified to only consider boundary points, which reduces the number
of points to consider. As part of this change, the reference point
is now always equivalent to the min of the bounding box, which
reduces the number of search loops. The merged points retain their
original order.
- inplaceMergePoints version to simplify use and improve code
robustness and efficiency.
ENH: make PrimitivePatch::boundaryPoints() less costly
- if edge addressing does not already exist, it will now simply walk
the local face edges directly to define the boundary points.
This avoids a rather large overhead of the full faceFaces,
edgeFaces, faceEdges addressing.
This operation is now more important since it is used in the revised
patch gatherAndMerge.
ENH: topological merge for mesh-based surfaces in surfaceFieldValue
- eliminate redundant size_ accounting
- drop extra 'Container' template parameter and replace functionality
with more flexible pack/unpack methods.
There is also a pack() method that handles indirect lists of lists
that can be used, for example, to pack a patch slice of faces.
Drop the 'operator()' method in favour of unpack to expose and properly
document the conversion. Should revisit the corresponding code in
some places for optimization potential.
- align some method names with globalIndex:
totalSize(), maxSize() etc
- the very old 'writer' class was fully stateless and always templated
on an particular output type.
This is now replaced with a 'coordSetWriter' with similar concepts
as previously introduced for surface writers (#1206).
- writers change from being a generic state-less set of routines to
more properly conforming to the normal notion of a writer.
- Parallel data is done *outside* of the writers, since they are used
in a wide variety of contexts and the caller is currently still in
a better position for deciding how to combine parallel data.
ENH: update sampleSets to sample on per-field basis (#2347)
- sample/write a field in a single step.
- support for 'sampleOnExecute' to obtain values at execution
intervals without writing.
- support 'sets' input as a dictionary entry (as well as a list),
which is similar to the changes for sampled-surface and permits use
of changeDictionary to modify content.
- globalIndex for gather to reduce parallel communication, less code
- qualify the sampleSet results (properties) with the name of the set.
The sample results were previously without a qualifier, which meant
that only the last property value was actually saved (previous ones
overwritten).
For example,
```
sample1
{
scalar
{
average(line,T) 349.96521;
min(line,T) 349.9544281;
max(line,T) 350;
average(cells,T) 349.9854619;
min(cells,T) 349.6589286;
max(cells,T) 350.4967271;
average(line,epsilon) 0.04947733869;
min(line,epsilon) 0.04449639927;
max(line,epsilon) 0.06452856475;
}
label
{
size(line,T) 79;
size(cells,T) 1720;
size(line,epsilon) 79;
}
}
```
ENH: update particleTracks application
- use globalIndex to manage original parcel addressing and
for gathering. Simplify code by introducing a helper class,
storing intermediate fields in hash tables instead of
separate lists.
ADDITIONAL NOTES:
- the regionSizeDistribution largely retains separate writers since
the utility of placing sum/dev/count for all fields into a single file
is questionable.
- the streamline writing remains a "soft" upgrade, which means that
scalar and vector fields are still collected a priori and not
on-the-fly. This is due to how the streamline infrastructure is
currently handled (should be upgraded in the future).
Automatic hole closure:
- introduces 'holeToFace' topoSet source
- used when detecting a 'leak-path'
- creates additional baffles to close the leak
Multi-stage layer addition:
- Can add layers in multiple passes
See issues: #2403, #2404
- refactor as an MPI-independent base class.
Add bufferIPC{send,recv} private methods for construct/destruct.
Eliminates code duplication from two constructor forms and reduces
additional constructor definitions in dummy library.
- add PstreamBuffers access methods, refactor common finish sends
code, tweak member packing
ENH: resize_nocopy for processorLduInterface buffers
- content is immediately overwritten
STYLE: cull unneeded includes in processorFa*
- handled by processorLduInterface
GIT: relocate globalIndex (is independent of mesh)
STYLE: include label/scalar Fwd in contiguous.H
STYLE: unneed commSchedule include in GeometricField
- add writer support for VERTICES
- updated use of globalIndex
ENH: add base vtk writer for points/verts/lines
STYLE: noexcept, explicit constructors etc
- when used with *any* alphaField and normalised (the usual case)
would largely give a 0-1 corresponding to the min/max of the first
component, but could also yield negative values.
- if the alpha field corresponds identically to colour field, it is
readily possible to combine as into RGBA sequences. However, if the
fields are different it potentially means referencing an opacity
field that has not yet been sampled. This impedes using the format
for a streaming sampler without additional overhead and/or rewriting
the alpha channel later.
- scene
- write with fileName, additional getMesh accessor
- addColourToMesh accepts an alpha field size 1 as a constant
alpha value
- sceneWriter wrapper
ENH: improve gltf handling of colour and alpha specification
- accept plain input directly.
Eg,
colour (1 0 1);
vs
colour uniform;
colourValue (1 0 1);
- use field magnitude for colouring of non-scalar fields.
Eg, having three different colour maps for a vector field simply
does not help much with visualisation.
- meshTools is the first layer in which coordSet is actually needed
STYLE: rename writer implementations in advance of upcoming changes (#2347)
- simplifies tracing of code changes (git blame)
ENH: provide fieldTypes::surface names (as per fieldTypes::volume)
ENH: reduce number of files for surface fields
- combine face and point field declarations/definitions,
simplify typeName definitions
- set() was silently deprecated in favour of reset() FEB-2018
since the original additional check for overwriting an existing
pointer was never used. The reset(...) name is more consistent
with unique_ptr, tmp etc.
Now emit deprecations for set().
- use direct test for autoPtr, tmp instead of valid() method.
More consistent with unique_ptr etc.
STYLE: eliminate redundant ptr() use on cloned quantities
- marks if the value is considered to be independent of 'x'.
Propagate into PatchFunction1 instead ad hoc checks there.
- adjust method name in PatchFunction1 to 'whichDb()' to reflect
final changes in Function1 method names.
ENH: add a Function1 'none' placeholder function
- This is principally useful for interfaces that expect a Function1
but where it is not necessarily used by a particular submodel.
TUT: update Function1 creation to use objectRegistry
