- provide no_topology() characteristic to avoid triggering potentially
expensive mesh connectivity calculations when they are not required.
- remove/deprecate unused pointField references from the renumber
methods. These appear to have crept in from outer similarities
with decompositionMethod, but have no meaning for renumbering.
- remove/deprecate various unused aggregation renumberings since these
have been previously replaced by pre-calling calcCellCells, or
using bandCompression directly.
- make regionFaceOrder for block-wise renumbering optional and
treat as experimental (ie, default is now disabled).
The original idea was to sort the intra-region and inter-region faces
separately. However, this will mostly lead to non-upper triangular
ordering between regions, which checkMesh and others don't really like.
ENH: add timing information for various renumberMesh stages
ENH: add reset of clockTime and cpuTime increment
- simplifies section-wise timings
ENH: add globalIndex::null() and fieldTypes::processorType conveniences
- provides more central management of these characteristics
- renumberMesh now has -dry-run, -write-maps, -no-fields,
-renumber-method, -renumber-coeffs options.
* Use -dry-run with -write-maps to visualize the before/after
effects of renumbering (creates a VTK file).
* -no-fields to renumber the mesh only.
This is useful and faster when the input fields are uniform
and the -overwrite option is specified.
* -renumber-method allows a quick means of specifying a different
default renumber method (instead of Cuthill-McKee).
The -renumber-coeffs option allows passing of dictionary content
for the method.
Examples,
// Different ways to specify reverse Cuthill-McKee
* -renumber-method RCM
* -renumber-coeffs 'reverse true;'
* -renumber-method CuthillMcKee
* -renumber-coeffs 'reverse true;'
* -renumber-coeffs 'method CuthillMcKee; reverse true;'
// Other (without dictionary coefficients)
* renumberMesh -renumber-method random
// Other (with dictionary coefficients)
renumberMesh \
-renumber-method spring \
-renumber-coeffs 'maxCo 0.1; maxIter 1000; freezeFraction 0.99;'
// Other (with additional libraries)
renumberMesh -renumber-method zoltan -lib zoltanRenumber
COMP: build zoltan renumbering to MPI-specific location
- zoltan and Sloan renumbering are now longer automatically linked to
the renumberMesh utility but must be separately loaded by a
command-line option or through a dictionary "libs" entry.
ENH: add output cellID for decomposePar -dry-run -cellDist
- retain group information when copying zones
- support construct empty (add details later)
- improve consistency for zone and boundaryMesh construction
- support front/back/both selection for faceZoneToCell
STYLE: prefer faceZone patch() method instead of operator()
STYLE: use std::unique_ptr instead of manual pointer management
- for zones and core patch types.
Easier data management, allows default destructors (for example)
- for simulations where the yPlus is needed for other purposes or
just for obtaining information on the patches it can be useful
to disable field writing and save disk space.
The 'writeFields' flag (as per some other function objects)
has been added control writing the yPlus volume field.
If unspecified, the default value is 'true' so that the yPlus
function object continues to work as before.
However, this default may change to 'false' in the future to align
with other function objects.
ENH: wallShearStress: support disable of field writing
- similar to yPlus, the write() method combines writing information
and writing the fields. The 'writeFields' flag allows some
separation of that logic.
- separate broadcast times from reduce/gather/scatter time
- separate wait times from all-to-all time
- support invocation counts, split off requests time/count
from others to avoid flooding the counts
- support 'detail' switch to increase the output information.
Format may change in the future
- 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'
- simpler to write for sampled cutting planes etc.
For example,
slice
{
type cuttingPlane;
point (0 0 0);
normal (0 0 1);
interpolate true;
}
instead of
slice
{
type cuttingPlane;
planeType pointAndNormal;
pointAndNormalDict
{
point (0 0 0);
normal (0 0 1);
}
interpolate true;
}
STYLE: add noexcept to some plane methods
- 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.
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
