subset(const UList<T>& select, const T& value, const ListType&);
inplaceSubset(const UList<T>& select, const T& value, ListType&);
The subsetList/inplaceSubsetList variants with a unary predicate
provide more flexible and robuster solutions.

Required prior to the addition of constructors with
std::initializer_list
* For most cases, this conversion would be largely unintentional
and also less efficient. If the regex is desirable, the caller
should invoke it explicitly.
For example,
findStrings(regExp(str), listOfStrings);
Or use one of the keyType, wordRe, wordRes variants instead.
If string is to be used as a plain (non-regex) matcher,
this can be directly invoked
findMatchingStrings(str, listOfStrings);
or using the ListOps instead:
findIndices(listOfStrings, str);
* provide function interfaces for keyType.
- subsetList, inplaceSubsetList with optional inverted logic.
- use moveable elements where possible.
- allow optional starting offset for the identity global function.
Eg, 'identity(10, start)' vs 'identity(10) + start'
- more consistent with STL practices for function classes.
- string::hash function class now operates on std::string rather
than Foam::string since we have now avoided inadvertent use of
string conversion from int in more places.
- Eg instead of using labelHashSet, used HashSet<label> which uses
the string::hash for hashing. Other places inadvertently using the
string::hash instead of Hash<label> for hashing.
STYLE: use Map<..> instead of HashTable<.., label, Hash<label>>
- reduces clutter
- add copy construct from UList
- remove copy construct from dissimilar types.
This templated constructor was too generous in what it accepted.
For the special cases where a copy constructor is required with
a change in the data type, now use the createList factory method,
which accepts a unary operator. Eg,
auto scalars = scalarList::createList
(
labels,
[](const label& val){ return 1.5*val; }
);
The tutorial demonstrates generation of a C-grid mesh using blockMesh
The geometry is provided by a surface mesh (OBJ file) of the NACA0012 aerofoil
The case is setup with a freestream flow speed of Ma=0.72
Thanks to Kai Bastos at Duke University for the geometry and helpful input.
Description
This boundary condition extrapolates field to the patch using the near-cell
values and adjusts the distribution to match the specified, optionally
time-varying, mean value. This extrapolated field is applied as a
fixedValue for outflow faces but zeroGradient is applied to inflow faces.
This boundary condition can be applied to pressure when inletOutlet is
applied to the velocity so that a zeroGradient condition is applied to the
pressure at inflow faces where the velocity is specified to avoid an
unphysical over-specification of the set of boundary conditions.
Usage
\table
Property | Description | Required | Default value
meanValue | mean value Function1 | yes |
phi | Flux field name | no | phi
\endtable
Example of the boundary condition specification:
\verbatim
<patchName>
{
type fixedMeanOutletInlet;
meanValue 1.0;
}
\endverbatim

These BCs blend between typical inflow and outflow conditions based on the
velocity orientation.
airFoil2D tutorial updated to demonstrate these new BCs.
In constant/chemistryProperties in addition to the specification of the initial
ODE integration time-step used at the start of the run:
initialChemicalTimeStep 1e-12;
this time step may now also be specified for every chemistry integration by
setting the optional entry maxChemicalTimeStep, e.g.
maxChemicalTimeStep 1e-12;
