- replaced PstreamBuffers mechanism with globalIndex for both gather
and scatter operations. Use scheduled communication by default, but
is selectable.
- reduced communication with ensemble averaging and no-write
- in makeFaMesh, the serial fields are now only read on the master
process and broadcast to the other ranks. The read+distribute is
almost identical to that used in redistributePar, except that in
this case entire fields are sent and not a zero-sized subset.
- improved internal faMesh checking for files so that the TryNew
method works with distributed roots.
- for repeated tests (eg, during bisection) can be used to preserve
the existing directory as tutorialsTest.bak01,
tutorialsTest.bak02, ... (max of 10).
- preserve the commit information as tutorialsTest/commit-info
to help document the current or backup test results.
- functionality similar to that provided by foamToEnsight, foamToVTK
which allows blocking out patches (eg, outer walls, inlet/outlet)
that are not particularly interesting to visualize
- new submodels:
- 'equalBinWidth': groups data into bins of equal widths (previous behaviour)
- 'unequalBinWidth': groups data into bins of unequal widths
- output files per time-step are replaced with a single output file
- silently deprecates the input entries: 'setFormat' and 'formatOptions'
- replaced ad hoc handling of formatOptions with coordSetWriter and
surfaceWriter helpers.
Accompanying this change, it is now possible to specify "default"
settings to be inherited, format-specific settings and have a
similar layering with surface-specific overrides.
- snappyHexMesh now conforms to setFormats
Eg,
formatOptions
{
default
{
verbose true;
format binary;
}
vtk
{
precision 10;
}
}
surfaces
{
surf1
{
...
formatOptions
{
ensight
{
scale 1000;
}
}
}
}
ENH: extend rmDir to handle removal of empty directories only
- recursively remove directories that only contain other directories
but no other contents. Treats dead links as non-content.
- in continuation of #2565 (rotationCentre for surface output formats)
it is helpful to also support READ_IF_PRESENT behaviour for the
'origin' keyword.
This can be safely used wherever the coordinate system definition
is embedded within a sub-dictionary scope.
Eg,
dict1
{
coordinateSystem
{
origin (0 0 0); // now optional here
rotation ...;
}
}
but remains mandatory if constructed without a sub-dict:
dict2
{
origin (0 0 0); // still mandatory
e1 (1 0 0);
e3 (0 0 1);
}
With this change, the "transform" sub-dictionary can written
more naturally:
formatOptions
{
vtk
{
scale 1000; // m -> mm
transform
{
rotationCentre (1 0 0);
rotation axisAngle;
axis (0 0 1);
angle -45;
}
}
}
ENH: simplify handling of "coordinateSystem" dictionary lookups
- coordinateSystems::NewIfPresent method for optional entries:
coordSysPtr_ = coordinateSystem::NewIfPresent(mesh, dict);
Instead of
if (dict.found(coordinateSystem::typeName, keyType::LITERAL))
{
coordSysPtr_ =
coordinateSystem::New
(
mesh_,
dict,
coordinateSystem::typeName
);
}
else
{
coordSysPtr_.reset();
}
ENH: more consistent handling of priorities for binModels, forces (#2598)
- if the dictionaries are overspecified, give a 'coordinateSystem'
entry a higher prioriy than the 'CofR' shortcuts.
Was previously slightly inconsistent between the different models.
- 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
- remedy by performing the attach() action sequentially (as per
stitchMesh changes). This ensures that the current point addressing
is always used and avoids references to the already-merged points
(which is what causes the failure).
ENH: improve handling of empty patch removal
- only remove empty *merged* patches, but leave any other empty
patches untouched since they may intentional placeholders for other
parts of a workflow.
- remove any empty point/face zones created for patch merging
- simplifies construction/inheritance
ENH: add {fa,fv}PatchField::zeroGradientType() static
- can be used to avoid literal "zeroGradient" in places
STYLE: adjust naming of pointPatch runtime selection table
- simply use 'patch' as per fa/fv fields
STYLE: add zero-size guard to patch constraintType(const word&)
- as an alternative output transform (supplementary to the regular
coordinate system specification - issue #2505) it is now possible to
specify the rotation centre directly.
Example:
formatOptions
{
vtk
{
scale 1000; // m -> mm
transform
{
origin (0 0 0);
rotationCentre (1 0 0);
rotation axisAngle;
axis (0 0 1);
angle -45;
}
}
}
This behaves like the transformPoints and surfaceTransformPoints
'-centre' option (formerly '-origin') in that it removes the
specified amount from the point locations, applies the rotation and
finally adds the specified amount back to the newly rotated point
locations.
The results of specifying a `rotationCentre` and a non-zero
coordinate system `origin` may not be intuitively evident.
When a finite-area case could not find an entry for "lnGradSchemes"
in the "faSchemes" file, the "corrected" scheme has been picked up
by default. Therefore, any changes in "snGradSchemes" entry will not
be read by finite-area models.
For example,
T
{
solver PBiCGStab;
preconditioner DILU;
tolerance 1e-6;
norm none;
}
STYLE: define defaultMaxIter, defaultTolerance directly in lduMatrix
- barycentric coordinates in interpolation (instead of x/y/z)
- ease U (velocity) requirement.
Needn't be named in the sampled fields.
- default tracking direction is 'forward'
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
