- surfaceWriter TryNew() factory methods for more failure tolerant
handling
- reduce communication for sampledSurfaces.
Track non-empty surfaces as bool, only updated on change
(expire/update).
- use Pstream::listScatterValues() instead of the old hand-rolled
method.
Reduces code and since it is mostly used with primitives it
will use MPI_Scatter directly (see #3087)
COMP: fix some inconsistent masterOp return types
- can use UList signature since the routines do not resize the list
or attempt to broadcast it: useful for SubList handling.
ENH: add IPstream/OPstream send/recv static methods
- related to issue #3095. Some type of geometry is required when
loading "measured" ensight data.
ENH: emit a fallback geometry-box for foamToEnsight
- eg, with "foamToEnsight -no-internal -no-boundary" and lagrangian
- process the contents of the cloud object registry, which enables
output support for calculated values such as Reynolds, Weber numbers
etc.
ENH: select any/all clouds by default instead of defaultCloud
- adds robustness
- the old Pstream::scatter routines (which were largely a misnomer)
have been superseded by various broadcast routines, but were left in
the code with #ifndef/#ifdef Foam_Pstream_scatter_nobroadcast
guards. Now noisily deprecate them, and remove the old manual tree
communication in favour of MPI broadcast and/or
serialize/de-serialize with wrapped Pstream::broadcast
- consolidate various gather methods to include the communication
structure directly. No functional change, but reduces the number of
methods.
ENH: add parallel guard to UPstream::whichCommunication() method
- returns List::null() as the schedule for non-parallel instead
of an inappropriate linear or tree schedule
ENH: Pstream::listGatherValues, Pstream::listScatterValues
- like the existing UPstream versions but supporting non-contiguous
- range(proci) instead of localStart(proci), localSize(proci) combination.
* does the same thing, can be used directly with various other
routines for slicing etc.
Eg,
Foam::identity(globalNumbering.range(myProci))
- globalIndex::calcOffset() instead of constructing a globalIndex and
taking the localStart(). Avoids intermediate resizing and storing of
an offsets table (which is then discarded) as well as the subsequent
lookup into that table
- 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
),
...
);
- can be useful when using memory-based streams for buffering,
in which case the name() can be used to specify the filesystem
location instead of the default stream names ("input", "output").
