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
- in makeFaMesh, the serial fields are now only read on the master
process and broadcast to the other ranks. The read+distribute is
almost identical to that used in redistributePar, except that in
this case entire fields are sent and not a zero-sized subset.
- improved internal faMesh checking for files so that the TryNew
method works with distributed roots.
- if the volume faceProcAddressing is missing, it is not readily
possible to determine equivalent area procAddressing.
Instead of throwing an error, be more fault-tolerant by having it
create with READ_IF_PRESENT and then detect and warn
if there are problems.
- accept IOobjectOption::registerOption with (MUST_READ, NO_WRITE)
being implicit. Direct handling of IOobjectOption itself, for
consistency with IOobject.
The disabling of object registration is currently the only case
where IOobjectList doesn't use default construction parameters,
but it was previously a bit awkward to specify.
- had an off-by-one in the accounting for some corner caes,
partly because the logic was a bit convoluted
ENH: improved string wrapping (#2625)
- reworked logic (like a state machine) to handle backtracking
with fallback of splitting near punctuation characters.
Still doesn't compete with nroff or TeX, but does avoid long lines
and many funny splits. With this change the help for mapFieldsPar
now like this:
=====
Specify the mapping method
(direct|mapNearest|cellVolumeWeight|
correctedCellVolumeWeight)
=====
Since the list of options is very long without any spaces, it takes
'|' as the best split point, which definitely reads better
- functionality similar to that provided by foamToEnsight, foamToVTK
which allows blocking out patches (eg, outer walls, inlet/outlet)
that are not particularly interesting to visualize
- since ensight format is always float and also always written
component-wise, perform the double -> float narrowing when
extracting the components. This reduces the amount of data
transferred between processors.
ENH: avoid vtk/ensight parallel communication of empty messages
- since ensight writes by element type (eg, tet, hex, polyhedral) the
individual written field sections will tend to be relatively sparse.
Skip zero-size messages, which should help reduce some of the
synchronization bottlenecks.
ENH: use 'data chunking' when writing ensight files in parallel
- since ensight fields are written on a per-element basis, the
corresponding segment can become rather sparsely distributed. With
'data chunking', we attempt to get as many send/recv messages in
before flushing the buffer for writing. This should make the
sequential send/recv less affected by the IO time.
ENH: allow use of an external buffer when writing ensight components
STYLE: remove last vestiges of autoPtr<ensightFile> for output routines
- with ATOMIC, an intermediary file is created - eg, (fileAbc~tmp~)
where all of the output is written to. When the stream goes out of
scope, this intermediary file is moved/renamed to the actually
output name - eg, (fileAbc~tmp~) -> (fileAbc).
This adds some safety if the simulation crashes while writing the
file, since it will the partial (corrupt) file will be left
behind as (fileAbc~tmp~) and not as (fileAbc), which means it will
will be treated as a backup file and not loaded again on restart.
ENH: provided enumeration for APPEND/NON_APPEND
- clearer than using bool (with comments).
Since append mode is primarily only used by masterOFstream etc
this change is unlikely to affect user coding.
ENH: use file atomic for ensight file creation
- avoids corrupt (truncated) files being referenced by the ensight
case file if the simulation crashes while writing the ensight file.
- eg, for partially incomplete systems (without libz devel header)
ENH: clearer binding of dummy Pstream in OpenFOAM/Make/options
- link of dummy stub Pstream now contingent on linking libOpenFOAM as
well. This makes the purpose slightly clearer
ENH: cleaner option naming/handling in wmake script
- allow special purpose -no-openfoam option.
Eg, compiling test programs without OpenFOAM and Pstream libraries
but using the rest of the wmake system.
ENH: add +openmp support into WM_COMPILE_CONTROL (#2633)
- this adds compile/link flags for openmp.
For single-use, can also use 'wmake -openmp'.
If both +openmp and ~openmp are specified in WM_COMPILE_CONTROL
the ~openmp will have priority.
This is actually done indirectly since ~openmp will set empty
COMP_OPENMP, LINK_OPENMP internal variables, which the +openmp then
adds to the c++FLAGS and linkexe targets (ie, won't actually add
anything).
ENH: add +ccache or ccache=... support into WM_COMPILE_CONTROL (#2633)
- with the first version (+ccache), simply use ccache from the path
without any extra options.
- with the second version (ccache=...), can be more specific about
what is called.
Using "+ccache" is identical to "ccache=ccache", but the later could
be used in other ways. For example,
ccache=/strange/install/path/ccache
ccache=</path/my-tooling --option>
Have the choice of unquoted, single or double quoted or '< >' quoted
STYLE: relocate FOAM_EXTRA_LDFLAGS in general makefile
- removes clutter for different linkers (eg, gold, mold, ldd)
making it easier to extend for other linkers.
STYLE: protect makefile checks with 'strip' function
- consistent with sumOp
ENH: globalIndex with gatherNonLocal tag, and use leading dispatch tags
- useful for gather/write where the master data can be written
separately. Leading vs trailing dispatch tags for more similarity to
other C++ conventions.
- new submodels:
- 'equalBinWidth': groups data into bins of equal widths (previous behaviour)
- 'unequalBinWidth': groups data into bins of unequal widths
- output files per time-step are replaced with a single output file
- silently deprecates the input entries: 'setFormat' and 'formatOptions'
The improvements include:
- Allowing overset patches to be displaced outside background domain.
- The approach does not support overlapping of multiple inset meshes
on top of background domain.
- Allowing fringe faces to walk away from hole cells in background domain.
- The approach was not extensibly tested with overlapping patches.
- Improving mass conservation.
- Various experimental entries are removed: massFluxInterpolation, ddtCorr.
- New entries:
- oversetAdjustPhi: adds a flux correction outside the pressure equation.
- massCorrection: adds an implicit correction.
- replaced ad hoc handling of formatOptions with coordSetWriter and
surfaceWriter helpers.
Accompanying this change, it is now possible to specify "default"
settings to be inherited, format-specific settings and have a
similar layering with surface-specific overrides.
- snappyHexMesh now conforms to setFormats
Eg,
formatOptions
{
default
{
verbose true;
format binary;
}
vtk
{
precision 10;
}
}
surfaces
{
surf1
{
...
formatOptions
{
ensight
{
scale 1000;
}
}
}
}
- for later reuse with fields (for example)
ENH: use 'scheduled' for surfaceWriter field merging (#2402)
- in tests with merging fields (surfaceWriter), 'scheduled' was
generally faster than 'nonBlocking' for scalars, minorly faster for
vectors.
Thus make 'scheduled' the default for the surfaceWriter but with a
user-option to adjust as required. Previously simply relied on
whichever default globalIndex had (currently nonBlocking).
Reuse globalIndex information from mergedSurf instead of
globalIndex::gatherOp to avoid an extra MPI call to gather sizes
each time.
These changes will not be noticable unless surface sampling is done
very frequently (eg, every iteration) and with large core counts.
- support globalIndex for points/faces as an output parameter,
which allows reuse in subsequent field merge operations.
- make pointMergeMap an optional parameter. This information is not
always required. Eg, if only using gatherAndMerge to combine faces
but without any point fields.
ENH: make globalIndex() noexcept, add globalIndex::clear() method
