* resize_null() methods for PtrList variants
- for cases where an existing PtrList needs a specific size and
but not retain any existing entries.
Eg,
ptrs.resize_null(100);
vs. ptrs.free(); ptr.resize(100);
or ptr.resize(100); ptrs.free();
* remove stored pointer before emplacing PtrList elements
- may reduce memory peaks
* STYLE: static_cast of (nullptr) instead of reinterpret_cast of (0)
* COMP: implement emplace_set() for PtrDynList
- previously missing, which meant it would have leaked through to the
underlying PtrList definition
* emplace methods for autoPtr, refPtr, tmp
- applies reset() with forwarding arguments.
For example,
tmp<GeoField> tfld = ...;
later...
tfld.emplace(io, mesh);
vs.
tfld.reset(new GeoField(io, mesh));
or
tfld.reset(tmp<GeoField>::New(io, mesh));
The emplace() obviously has reduced typing, but also allows the
existing stored pointer to be deleted *before* creating its
replacement (reduces memory peaks).
- this simplifies polling receives and allows separation from
the sends
ENH: add UPstream::removeRequests(pos, len)
- cancel/free of outstanding requests and remove segment from the
internal list of outstanding requests
- removed gatherv control.
The globalIndex information is cached on the merged surface
and thus not triggered often.
- strip out debug mergeField method which was a precursor to
what is now within surfaceWriter itself.
- add 'merge' true/false handling to allow testing without
parallel merging (implies no writing)
- continue to support spherical by default (for compatibility)
but add the 'spherical' switch to disable that and use a cubic
distribution instead.
STYLE: reduce number of inline files

- can be used, for example, to track global states:
// Encode as 0:empty, 1:uniform, 2:nonuniform, 3:mixed
PackedList<2> uniformity(fields.size());
forAll(fields, i)
{
uniformity.set(i, fields[i].whichUniformity());
}
reduce
(
uniformity.data(),
uniformity.size_data(),
bitOrOp<unsigned>()
);
- can reduce communication by only sending non-zero data (especially
when using NBX for size exchanges), but proper synchronisation with
multiply-connected processor/processor patches (eg, processorCyclic)
may still require speculative sends.
Can now setup for PstreamBuffers 'registered' sends to avoid
ad hoc bookkeeping within the caller.
- simplifies code by avoiding code duplication:
* parLagrangianDistributor
* meshToMesh (processorLOD and AABBTree methods)
BUG: inconsistent mapping when using processorLOD boxes (fixes#2932)
- internally the processorLODs createMap() method used a 'localFirst'
layout whereas a 'linear' order is what is actually expected for the
meshToMesh mapping. This will cause of incorrect behaviour
if using processorLOD instead of AABBTree.
A dormant bug since processorLOD is not currently selectable.
- when constructing from a sendMap, can now also specify a linear
receive layout instead of a localFirst layout
This will make it easier to reduce some code (#2932)
- add missing interface for simple distribute of List/DynamicList
with a specified commsType. Was previously restricted to
defaultCommsType only.
ENH: mapDistribute distribute/reverseDistribute with specified commsType
STYLE: prefer UPstream vs Pstream within mapDistribute
- replaces previous (similar) union but leverages the type tag for
handling logic
STYLE: remove unneeded refCount from exprResult
COMP: operator!= as member operator (exprResultDelayed, exprResultStored)
- the operator!= as a free function failed to resolve after removing
the refCount inheritance
- primarily for handling expression results,
but can also be used as a universal value holder.
Has some characteristics suitable for type-less IO:
eg, is_integral(), nComponents()
ENH: add is_pointer() check for expression scanToken
- handle existence/non-existence of a FoamFile header automatically
- support an upper limit when getting the number of blocks and
use that for a hasBlock(...) method, which will stop reading sooner.
- Time is normally constructed with READ_MODIFIED for its controlDict
and objectRegistry, but for certain applications (eg, redistributePar)
it can be useful to construct without file monitoring and specifying
MUST_READ instead.
Example,
Info<< "Create time\n" << Foam::endl;
Time runTime
(
Time::controlDictName,
args,
false, // Disallow functionObjects
true, // Allow controlDict "libs"
IOobjectOption::MUST_READ // Instead of READ_MODIFIED
);
- update TimeState access methods
- use writeTime() instead of old method name outputTime()
- use deltaTValue() instead of deltaT().value()
to avoids pointless construct of intermediate
- no change in behaviour except to emit a warning when called with the
a non-reading readOption
STYLE: remove redundant size check
- size checking is already done by Field::assign() within the
DimensionedField::readField
- commit fb69a54bc3 accidentally changed the constructMap compact
order from linear ordering to local elements first order. Seems to
interact poorly with other bookkeeping so doing a partial revert,
but still replacing the old allGatherList with exchangeSizes.
Note:
the processorLOD method does actually use a constructMap with local
elements first ordering, so some inconsistency may still exist
there
Corrects turbulence viscosity field (e.g. nut) within a specified
region by applying a maximum limit, set according to a coefficient
multiplied by the laminar viscosity:
\nu_{t,max} = c \nu
Corrections applied to:
nut | Turbulence vicosity [m2/s2]
Usage
Minimal example by using \c constant/fvOptions:
\verbatim
limitTurbulenceViscosity1
{
// Mandatory entries (unmodifiable)
type limitTurbulenceViscosity;
// Optional entries (runtime modifiable)
nut nut;
c 1e5;
// Mandatory/Optional (inherited) entries
...
}
The optional areaNormalisationMode entry determines how the area normalisation
is performed. Options are:
- `project`: tri face area dotted with patch face normal; same as v2212 (default)
- `mag`: tri face area magnitude (v2206 and earlier)
Example usage:
AMI1
{
type cyclicAMI;
...
areaNormalisationMode mag;
//areaNormalisationMode project;
}
- the special MacOS dlopen handling (commit f584ec97d0)
did not fully solve the problem with SIP clearing.
Eg, sourcing the RunFunctions (for runParallel) triggers SIP and
clears DYLD_LIBRARY_PATH. With the cleared path it finds the dummy
libraries: the dummy Pstream::init() fails.
