- CompactListList::size() corresponds to the number of sub-lists
whereas globalIndex::size() corresponds to the totalSize().
This difference can lead to potential coding errors when switching
between pure addressing (eg globalIndex) and addressing with content
(eg, CompactListList).
Within the source tree, there are no longer any occurances of
globalIndex::size() but it is nonetheless unsafe to change its
meaning now. Instead provide a commonly named length() method that
corresponds to the natural length: ie, the number of offsets minus 1
(with guards).
- add CompactListList::writeMatrix for writing the compact contents
in an unpacked form (eg, for debugging) without actually needing to
unpack into storage.
- provide globalIndex::whichProcID() two-parameter version
with myProcNo as the first argument.
Symmetric with isLocal etc, useful when using a communicator
that is not worldComm.
- avoids clutter of argList::envGlobalPath() ...
ENH: allow temporary overwriting of output writeFormat
- allows switching for particular output routines
COMP: explicitly use TimePaths methods with Time
- this simplifies any overloading done at a later stage
- remnant was left in the NBX implementation for Map<Type>.
Still not entirely certain which vendors/versions handle message
probe/recv properly, but using the "regular" probe and recv is OK
since everything is without threaded race conditions.
STYLE: adjust file extension of UPstreamWrapping templates
- avoids it being exposed via lnInclude
- this makes it easier to split creation into a two-stage process
as required
- extend handling for polyBoundaryMeshEntries, faBoundaryMeshEntries
with more functionality. Ensure that these are never registered.
ENH: addition writeEntry methods for polyBoundaryMesh
- simplifies streaming and collating into other files
ENH: polyMesh rereading - update owner/neighbour header information
- this avoids accidentally reading the "cells" file if the mesh has
been created with NO_READ and then updated
STYLE: less vertical space when outputting empty PtrList
- combined most of the unweighted and weighted decomposition routines
such that an empty weight field is treated as uniform weighting.
This allows default parameters and cuts down on the number of
decompose methods.
- for topology-driven decomposition, it is now possible to pass in the
owner/neighbour connectivity as a CompactListList directly instead
of first creating a labelListList (which was internally repacked into
a CompactListList in many cases).
However, multiLevelDecomp still uses unpacking (to avoid a larger
reworking of code).
- support direct creation of some methods (eg, random, scotch etc)
without a dictionary
- fix incorrect neighbour face weighting (fixes#3019)
ENH: relocate calcCellCells from decompositionMethod to globalMeshData
- makes it more universally available
- usually only need big/little defines (which are now in the Fwd)
and rarely need byte-swapping.
Provide endian.H compatibility include, but foamEndianFwd.H or
foamEndian.H to avoid potential name clashes.
- The pTraits_cmptType returns the data type of 'cmptType' (for
arithmetic and VectorSpace types) or is simply a pass-through.
This can be combined with the pTraits_nComponents for casting.
For example,
function
(
reinterpret_cast<pTraits_cmptType<Type>::type*>(buf.data()),
(buf.size()/pTraits_nComponents<Type>::value)
);
ENH: extend Foam::identityOp so support array indexing (pass-through)
- single() method : simply tests if the globalIndex has nProcs == 1,
which is typically from a gatherNone invocation.
For example,
globalIndex gi;
if (...) gi.reset(localSize);
else gi.reset(globalIndex::gatherNone{}, localSize);
// later...
const label begin = (gi.single() ? 0 : gi.localStart());
const label count = (gi.single() ? gi.totalSize() : gi.localSize());
- add front() and back() methods to return the begin/end ranges,
and begin_value(), end_value() - as per labelRange.
- make more methods noexcept
- calcOffset(), calcRange() helper functions to determine
the processor-local of a numbering range without the overhead of
creating a list of offsets.
For example,
label myOffset = globalIndex::calcOffset(mesh.nCells());
labelRange mySlice = globalIndex::calcRange(mesh.nCells());
- add globalIndex localEnd() as per CompactListList method
STYLE: align looping constructs in CompactListList with List
- make more methods noexcept
- becoming more frequently used and there is no ambiguity in calling
parameters either - identity(label) vs identity(labelUList&).
Provide both int32 and int64 versions.
- it seems that both sides of the ternary are evaluated despite
the divide-by-zero protection. Use volatile to force the compiler
to use in-order evaluation.
- attempt to minimize rounding in the cached time values
since these are also used to re-populate the case files
STYLE: remove ancient handling of "meshes" entry
- was superseded by "geometry" entry in OpenFOAM-1912 and later.
Now remove the transitional shim, which was in place for
restart migration from 1906.
CONFIG: downgrade non-uniform time from error to warning
- can be a spurious error when the deltaT is very small
CONFIG: support keywords 'minFreq', 'maxFreq'
- these are the updated naming for 'fl' and 'fu' (still supported)
- new format option keywords: timeFormat, timePrecision
CONFIG: default ensight output is now consistently BINARY
- this removes some uncertainty with the ensightWrite functionObject
which was previously dependent on the simulation writeFormat
and makes its behaviour consistent with foamToEnsight
Note: binary Ensight output is consistent with the
defaults for VTP output (inline binary)
ENH: minor adjustment of ensight writing methods
- retain group information when copying zones
- support construct empty (add details later)
- improve consistency for zone and boundaryMesh construction
- support front/back/both selection for faceZoneToCell
STYLE: prefer faceZone patch() method instead of operator()
STYLE: use std::unique_ptr instead of manual pointer management
- for zones and core patch types.
Easier data management, allows default destructors (for example)
- use add_tokens() instead of the old multi-parameter
append(.., bool) method which was misleading since it added tokens
at the current tokenIndex, not at the end.
- stringify ITstream contents with CharStream instead of StringStream.
Allows string_view for copying out the content.
ENH: set namedDictionary dictionary name from Istream
- provides context for error messages etc (#2990)
- now mark methods with strict deprecation, to make it easier to find
their use but without adding extra compilation noise for others
ENH: minor update for Enum methods and iterator
- add warnOnly (failsafe) option for readEntry and getOrDefault
- add good() method to Enum iterator (simliar to HashTable)
- replace unused/fragile Enum find() methods with iterator return
that can be used more generally
- explicit use of UPstream::worldComm in globalIndex methods
for more clarity
- adjust method declaration ordering:
de-emphasize the processor-local convenience methods
- consistent use of leading tag dispatch,
remove unused enum-based dispatch tag
- add begin()/cbegin() with offset (as per List containers)
BUG: missing use of communicator in globalIndex gatherNonLocal
- does not affect any existing code (which all use worldComm anyhow)
