Description:
The plicRDF interface reconstruction scheme calculates a reconstructed distance
function (RDF) in all interface cells and their point neighbours.
In point neighbours to interface cells, the RDF is calculated as a weighted
average of the distances to all adjacent interface cell centres with the weight
being the inverse distance to the cell centre.
By using the zoneDistribute class written by Henning Scheufler, the required
stencil data is communicated efficiently for stencil cells living on different
sides of one or more processor patches.
Some of the data required for the RDF reconstruction are cell centre and
interface centre positions. When a stencil extends across a cyclic patch these
positions have so far not been properly transformed in OpenFOAM. This issue is
fixed by the current contribution.
The fix is done by modifying the zoneDistribute class to hold the required
information about zone cells adjacent to cyclic patches. Positions are then
communicated with a new getPosition function which replaces getValue for
position data in the reconstructedDistanceFunction and plicRDF classes.
The implementation does not change the behaviour for cells not on
a cyclic patch and should have insignificant effect on efficiency for these.
The implementation can probably be optimised in terms of efficiency for zone
cells on cyclic patches, but we note that there are generally only very few of
these (interface cells and their point neighbours on cyclic patches) and so
the potential for speedup is expected to be limited.
Current limitations:
- In parallel, the user must constrain the decomposition to preserve cyclic
patches on the same processor, for the implementation to work properly.
- See an example here: tutorials/discInConstantFlowCyclicBCs/system/decomposeParDict
- In the case of parallel rotational cyclics that are split by the decomposition
the current bugfix does not work and therefore throws an error. This is ongoing
work and should be reported and fixed by a future patch.

- 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 example,
defaultFieldValues
(
areaScalarFieldValue h 0.00014
);
regions
(
clipPlaneToFace
{
point (0 0 0);
normal (1 0 0);
fieldValues
(
areaScalarFieldValue h 0.00015
);
}
);
ENH: additional clipPlaneTo{Cell,Face,Point} topo sets
- less cumbersome than defining a semi-infinite bounding box
phaseSystemModels function objects are relocated within
functionObjects in order to enable broader usage.
ENH: multiphaseInterHtcModel: new heatTransferCoeff function object model
COMP: createExternalCoupledPatchGeometry: add new dependencies
COMP: alphaContactAngle: avoid duplicate entries between multiphaseEuler and reactingEuler
TUT: damBreak4Phase: rename alphaContactAngle as multiphaseEuler::alphaContactAngle
- include constant/faMesh cleanup (cleanFaMesh) as part of standard
cleanCase
- simplify cleanPolyMesh function to now just warn about old
constant/polyMesh/blockMeshDict but not try to remove anything
- cleanup cellDist.vtu (decomposePar -dry-run) as well
ENH: foamRunTutorials - fallback to Allrun-parallel, Allrun-serial
TUT: call m4 with file argument instead of redirected stdin
TUT: adjust suffixes on decomposeParDict variants
- can specify rotations that are not "axes" in a compact form:
transform
{
origin (0 0 0);
rotation none;
}
transform
{
origin (0 0 0);
rotation axisAngle;
axis (0 0 1);
angle 45;
}
An expanded dictionary form also remains possible:
transform
{
origin (0 0 0);
rotation
{
type axisAngle;
axis (0 0 1);
angle 45;
}
}
STYLE: verbose deprecation for "coordinateRotation" keyword
- the "coordinateRotation" keyword was replaced by the "rotation"
keyword (OpenFOAM-v1812 and later) but was handled silently.
Now elevated to non-silent.
STYLE: alias lookups "axesRotation", "EulerRotation", "STARCDRotation"
- these warn and report the equivalent short form, which aids in
upgrading. Previously had silent lookups.
- can be more intuitive to specify for some cases:
rotation
{
type euler;
order rollPitchYaw;
angles (0 20 45);
}
- refactor starcd rotation to reuse Euler ZXY ordering
(code reduction)
ENH: add -rotate-x, -rotate-y, -rotate-z for transformPoints etc
- easier to specify for simple rotations
- 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
- 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
The turbulentTemperatureCoupledBaffleMixed boundary condition
has been superseded by the turbulentTemperatureRadCoupledMixed condition
TUT: injectorPipe: remove an unused entry
TUT: waveMakerFlap: remove uncompressed entry
- marks if the value is considered to be independent of 'x'.
Propagate into PatchFunction1 instead ad hoc checks there.
- adjust method name in PatchFunction1 to 'whichDb()' to reflect
final changes in Function1 method names.
ENH: add a Function1 'none' placeholder function
- This is principally useful for interfaces that expect a Function1
but where it is not necessarily used by a particular submodel.
TUT: update Function1 creation to use objectRegistry
