- "buffered" corresponds to MPI_Bsend (buffered send),
whereas the old name "blocking" is misleading since the
regular MPI_Send also blocks until completion
(ie, buffer can be reused).
ENH: IPstream::read() returns std::streamsize instead of label (#3152)
- previously returned a 'label' but std::streamsize is consistent with
the input parameter and will help with later adjustments.
- use <label> instead of <int> for internal accounting of the message
size, for consistency with the underyling List<char> buffers used.
- improve handling for corner case of IPstream receive with
non-blocking, although this combination is not used anywhere
- findStrings, findMatchingStrings now mostly covered by matching
intrinsics in wordRe and wordRes.
Add static wordRes match() and matching() variants
COMP: remove stringListOps include from objectRegistry.H
- was already noted for removal (NOV-2018)
ENH: eliminate unnecessary duplicate communicator
- in globalMeshData previously had a comm_dup hack to avoid clashes
with deltaCoeffs calculations. However, this was largely due to a
manual implementation of reduce() that used point-to-point
communication. This has since been updated to use an MPI_Allreduce
and now an MPI_Allgather, neither of which need this hack.
- creates an IOobject at the current time instance (timeName) with
NO_READ/NO_WRITE/NO_REGISTER characteristics.
This generalises and replaces the Cloud fieldIOobject() to simplify
some common use.
// Shorter version (new):
volScalarField fld
(
mesh.newIOobject(name),
...
);
// Longer version:
volScalarField fld
(
IOobject
(
name,
mesh.time().timeName(),
mesh,
IOobject::NO_READ,
IOobject::NO_WRITE
IOobject::NO_REGISTER
),
...
);
- use Foam::zero as a dispatch tag
FIX: return moleculeCloud::constProps() List by reference not copy
STYLE: range-for when iterating cloud parcels
STYLE: more consistent typedefs / declarations for Clouds
- static version of polyMesh::meshDir(), which takes a region name
polyMesh::meshDir(regionName)
vs
polyMesh::regionName(regionName)/polyMesh::meshSubDir
STYLE: use polyMesh::regionName(..) instead of comparing to defaultRegion
STYLE: use getOrDefault when retrieving various -region options
FIX: polyMesh::dbDir() now checks registry name, not full path (#3033)
- for workflows with appearing/disappearing patches (for example)
can specify that empty surfaces should be ignored or warned about
instead of raising a FatalError.
Note that this handling is additional to the regular top-level
"errors" specification. So specifying 'strict' will only actually
result in a FatalError if the "errors" does not trap errors.
- "ignore" : any empty surfaces are simply ignored and no
file output (besides the header).
- "warn" : empty surfaces are warned about a few times (10)
and the file output contains a NaN entry
- "strict" : corresponds to the default behaviour.
Throws a FatalError if the surface is empty.
This error may still be caught by the top-level "errors" handling.
- in most cases a parallel-consistent order is required.
Even when the order is not important, it will generally require
fewer allocations to create a UPtrList of entries instead of a
HashTable or even a wordList.
- update TimeState access methods
- use writeTime() instead of old method name outputTime()
- use deltaTValue() instead of deltaT().value()
to avoids pointless construct of intermediate
- for simulations where the yPlus is needed for other purposes or
just for obtaining information on the patches it can be useful
to disable field writing and save disk space.
The 'writeFields' flag (as per some other function objects)
has been added control writing the yPlus volume field.
If unspecified, the default value is 'true' so that the yPlus
function object continues to work as before.
However, this default may change to 'false' in the future to align
with other function objects.
ENH: wallShearStress: support disable of field writing
- similar to yPlus, the write() method combines writing information
and writing the fields. The 'writeFields' flag allows some
separation of that logic.
- for boundary conditions such as uniformFixed, uniformMixed etc the
optional 'value' entry (optional) is used for the initial values and
restarts. Otherwise the various Function1 or PatchFunction1 entries
are evaluated and used determine the boundary condition values.
In most cases this is OK, but in some case such coded or expression
entries with references to other fields it can be problematic since
they may reference fields (eg, phi) that have not yet been created.
For these cases the 'value' entry will be needed: documentation
updated accordingly.
STYLE: eliminate some unneeded/unused declaration headers
- use typeHeaderOk<regIOobject>(false) for some generic file existence
checks. Often had something like labelIOField as a placeholder, but
that may be construed to have a particular something.
- attributes such as assignable(), coupled() etc
- common patchField types: calculatedType(), zeroGradientType() etc.
This simplifies reference to these types without actually needing a
typed patchField version.
ENH: add some basic patchField types to fieldTypes namespace
- allows more general use of the names
ENH: set extrapolated/calculated from patchInternalField directly
- avoids intermediate tmp
ENH: add pTraits and IO for std::int8_t
STYLE: cull some implicitly available includes
- pTraits.H is included by label/scalar etc
- zero.H is included by UList
STYLE: cull redundant forward declarations for Istream/Ostream
