ENH: additional topoSet "ignore" action
- this no-op can be used to skip an action step, instead of removing
the entire entry
- this allows more flexibility when defining the location or intensity
of sources.
For example,
{
type scalarSemiImplicitSource;
volumeMode specific;
selectionMode all;
sources
{
tracer0
{
explicit
{
type exprField;
functions<scalar>
{
square
{
type square;
scale 0.0025;
level 0.0025;
frequency 10;
}
}
expression
#{
(hypot(pos().x() + 0.025, pos().y()) < 0.01)
? fn:square(time())
: 0
#};
}
}
}
}
ENH: SemiImplicitSource: handle "sources" with explicit/implicit entries
- essentially the same as injectionRateSuSp with Su/Sp,
but potentially clearer in purpose.
ENH: add Function1 good() method to define if function can be evaluated
- for example, provides a programmatic means of avoiding the 'none'
function
- similar to the geometric decomposition constraint,
allows a compositing selection of cells based on topoSet sources
which also include various searchableSurface mechanisms.
This makes for potentially easier placement of sources without
resorting to defining a cellSet.
ENH: support zone group selection for fv::cellSetOption and fa::faceSetOption
Reports cloud information for particles passing through a specified cell
zone.
Example usage:
cloudFunctions
{
particleZoneInfo1
{
type particleZoneInfo;
cellZone leftFluid;
// Optional entries
//writer vtk;
}
}
Results are written to file:
- \<case\>/postProcessing/lagrangian/\<cloudName\>/\<functionName\>/\<time\>
\# cellZone : leftFluid
\# time : 1.0000000000e+00
\#
\# origID origProc (x y z) time0 age d0 d mass0 mass
Where
- origID : particle ID
- origProc : processor ID
- (x y z) : Cartesian co-ordinates
- time0 : time particle enters the cellZone
- age : time spent in the cellZone
- d0 : diameter on entry to the cellZone
- d : current diameter
- mass0 : mass on entry to the cellZone
- mass : current mass
If the optional \c writer entry is supplied, cloud data is written in the
specified format.
During the run, output statistics are reported after the cloud solution,
e.g.:
particleZoneInfo:
Cell zone = leftFluid
Contributions = 257
Here, 'Contributions' refers to the number of incremental particle-move
contributions recorded during this time step. At write times, the output
is extended, e.g.:
particleZoneInfo:
Cell zone = leftFluid
Contributions = 822
Number of particles = 199
Written data to "postProcessing/lagrangian/reactingCloud1/
TUT: filter: add an example for the particleZoneInfo function object
- Previously, the multiFieldValue function object was limited to operate on
lists of fieldValue function objects.
- Any function objects that generate results can now be used, e.g.
pressureAverage
{
type multiFieldValue;
libs (fieldFunctionObjects);
operation average;
functions
{
inlet
{
type surfaceFieldValue;
operation areaAverage;
regionType patch;
name inlet;
fields (p);
writeFields no;
writeToFile no;
log no;
resultFields (areaAverage(inlet,p));
}
outlet
{
type surfaceFieldValue;
operation areaAverage;
regionType patch;
name outlet;
fields (p);
writeFields no;
writeToFile no;
log no;
}
average
{
type valueAverage;
functionObject testSample1;
fields (average(p));
writeToFile no;
log no;
}
}
}
TUT: cavity: add an example for the multiFieldValue function object
Two problems:
- flipping inside snappyHexMesh is not done in a parallel
consistent way. So e.g. the octree-cached inside/outside information
has already been calculated. For now flipping of
distributedTriSurfaceMesh is disabled.
- octree-cached inside/outside information was using already
cached information and would only work for outwards pointing
volumes
- can now specify sampled sets as dictionary entries instead of a list
entry.
can now use: sets { ... }
instead of: sets ( ... );
This is similar to sampled surfaces and makes it easier to
manage with dictionary manipulation tools.
TUT: update to use writeTime instead of outputTime
Automatic hole closure:
- introduces 'holeToFace' topoSet source
- used when detecting a 'leak-path'
- creates additional baffles to close the leak
Multi-stage layer addition:
- Can add layers in multiple passes
See issues: #2403, #2404
- the internal data are contiguous so can broadcast size and internals
directly without an intermediate stream.
ENH: split out broadcast time for profilingPstream information
STYLE: minor Pstream cleanup
- UPstream::commsType_ from protected to private, since it already has
inlined noexcept getters/setters that should be used.
- don't pass unused/unneed tag into low-level MPI reduction templates.
Document where tags are not needed
- had Pstream::broadcast instead of UPstream::broadcast in internals
- now largely encapsulated using PstreamBuffers methods,
which makes it simpler to centralize and maintain
- avoid building intermediate structures when sending data,
remove unused methods/data
TUT: parallel version of depthCharge2D
STYLE: minor update in ProcessorTopology
- this can be used to apply a uniform field level to remove from
a sampled field. For example,
fieldLevel
{
"p.*" 1e5; // Absolute -> gauge [Pa]
T 273.15; // [K] -> [C]
U #eval{ 10/sqrt(3) }; // Uniform mag(U)=10
}
After the fieldLevel has been removed, any fieldScale is applied.
For example
fieldScale
{
"p.*" 0.01; // [Pa] -> [mbar]
}
The fieldLevel for vector and tensor fields may still need some
further refinement.
- when used with *any* alphaField and normalised (the usual case)
would largely give a 0-1 corresponding to the min/max of the first
component, but could also yield negative values.
- if the alpha field corresponds identically to colour field, it is
readily possible to combine as into RGBA sequences. However, if the
fields are different it potentially means referencing an opacity
field that has not yet been sampled. This impedes using the format
for a streaming sampler without additional overhead and/or rewriting
the alpha channel later.
- supports sampling/probing of values to obtain min/max/average/size
at execution intervals without writing any output or generating
output directories.
- 'verbose' option for additional output
The parcel initial velocity can now be set using the new `velocityType`
entry, taking one of the following options:
- fixedValue : (default) same as earlier versions, requires U0
- patchValue : velocity set to seed patch face value
- zeroGradient : velocity set to seed patch face adjacent cell value
Example usage:
model1
{
type patchInjection;
massTotal 1;
SOI 0;
parcelBasisType mass;
patch cylinder;
duration 10;
parcelsPerSecond 100;
velocityType patchValue;
//velocityType zeroGradient;
//U0 (-10 0 0);
flowRateProfile constant 1;
sizeDistribution
{
type normal;
normalDistribution
{
expectation 1e-3;
variance 1e-4;
minValue 1e-5;
maxValue 2e-3;
}
}
}
