- The edgeInterpolation::makeCorrectionVectors() disables the non-orthogonality
correction if the calculated non-orthogonality coefficient is below 0.1.
However, this activation routine only considers internal edges, and excludes
any processor edges, resulting in inconsistent parallel calculations. This
routine is removed.
- Fatal errors are replaced with zero-valued fields for non-orthogonality-
and skewness-correction routines.
- 1_Inlet_2_Outlet/porosityBased/R_10x-init/reEval: showcases the
initialization of the design variables using topoSet and setFields
- 3DBox/losses-mass-uniformity-SQP-extraVars: showcases the use of the
so-called 'extra variables' in the QP problem which relax it,
allowing its solution even if there is no feasible one
- the timeSelector is often used to select single or multiple times
(eg, for post-processing). However, there are a few applications
where only a *single* time should be selected and set.
These are now covered by this type of use:
timeSelector::addOptions_singleTime(); // Single-time options
...
// Allow override of time from specified time options, or no-op
timeSelector::setTimeIfPresent(runTime, args);
In some cases, if can be desirable to force starting from the
initial Time=0 when no time options have been specified:
// Set time from specified time options, or force start from Time=0
timeSelector::setTimeIfPresent(runTime, args, true);
These changes make a number of includes redundant:
* addTimeOptions.H
* checkConstantOption.H
* checkTimeOption.H
* checkTimeOptions.H
* checkTimeOptionsNoConstant.H
ENH: add time handling to setFields, setAlphaField (#3143)
Co-authored-by: Johan Roenby <>
STYLE: replace instant("constant") with instant(0, "constant")
- avoids relying on atof parse behaviour returning zero
- used defunct "processors/" directory naming, and includes are now
addressed by the file-handler anyhow.
ENH: support 'tutorials/Alltest -init'
- for copying/creating test directory without running
- 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

equations

conditions were actually using the same U
- topology optimisation: tutorials designed to show the impact of the
flow rate distribution were actually using the same target
fractions

- the fileHandler changes included setting cacheLevel(0) to avoid
blocking with redistributePar. However, this meant if clouds
were not uniformly present on all ranks the fileHandler would follow
different code paths and lead to blocking.
Now switch to distributed mode for the lagrangian operations within
redistributePar based on the cacheLevel information.
FIX: avoid triggering a false processor check in argList
- when redistributing to few ranks
