- can use traits to distinguish label vs scalar types and
setComponents to properly index into single or multi-component
types without needing template specialisations for the task.
This avoids the need for a concrete translation unit and the
reported problem of multiply-defined specialisations when the header
is included in different places.
ENH: add pTraits and IO for std::int8_t
STYLE: cull some implicitly available includes
- pTraits.H is included by label/scalar etc
- zero.H is included by UList
STYLE: cull redundant forward declarations for Istream/Ostream
- background: for some application it can be useful to have fully
sorted points. i.e., sorted by x, followed by y, followed by z.
The default VectorSpace 'operator<' compares *all*
components. This is seen by the following comparisons
1. a = (-2.2 -3.3 -4.4)
b = (-1.1 -2.2 3.3)
(a < b) : True
Each 'a' component is less than each 'b' component
2. a = (-2.2 -3.3 -4.4)
b = (-2.2 3.3 4.4)
(a < b) : False
The a.x() is not less than b.x()
The static definitions 'less_xyz', 'less_yzx', 'less_zxy'
instead use comparison of the next components as tie breakers
(like a lexicographic sort).
- same type of definition that Pair and Tuple2 use.
a = (-2.2 -3.3 -4.4)
b = (-2.2 3.3 4.4)
vector::less_xyz(a, b) : True
The a.x() == b.x(), but a.y() < b.y()
They can be used directly as comparators:
pointField points = ...;
std::sort(points.begin(), points.end(), vector::less_zxy);
ENH: make VectorSpace named access methods noexcept.
Since the addressing range is restricted to enumerated offsets
(eg, X/Y/Z) into storage, always remains in-range.
Possible to make constexpr with future C++ versions.
STYLE: VectorSpace 'operator>' defined using 'operator<'
- standard rewriting rule
- previously had 'mandatory' (bool) for advanced control of reading
dictionary entries but its meaning was unclear in the calling code
without extra code comments.
Now use IOobjectOption::readOption instead, which allows further
options (ie, NO_READ) and is more transparent as to its purpose in
the code than a true/false bool flag was.
This is a minor breaking change (infrequent, advanced usage only)
- minor code cleanup in dictionary lookup methods
STYLE: qualify format/version/compression with IOstreamOption not IOstream
STYLE: reduce number of lookups when scanning {fa,fv}Solution
STYLE: call IOobject::writeEndDivider as static
- this allows more flexibility when defining the location or intensity
of sources.
For example,
{
type scalarSemiImplicitSource;
volumeMode specific;
selectionMode all;
sources
{
tracer0
{
explicit
{
type exprField;
functions<scalar>
{
square
{
type square;
scale 0.0025;
level 0.0025;
frequency 10;
}
}
expression
#{
(hypot(pos().x() + 0.025, pos().y()) < 0.01)
? fn:square(time())
: 0
#};
}
}
}
}
ENH: SemiImplicitSource: handle "sources" with explicit/implicit entries
- essentially the same as injectionRateSuSp with Su/Sp,
but potentially clearer in purpose.
ENH: add Function1 good() method to define if function can be evaluated
- for example, provides a programmatic means of avoiding the 'none'
function
- 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
Returns a 0/1 value corresponding to function object trigger levels.
Usage:
\verbatim
<entryName> functionObjectTrigger;
<entryName>Coeffs
{
triggers (1 3 5);
defaultValue false; // Default when no triggers activated
}
\endverbatim
ENH: add reset() method for Constant Function1
ENH: allow forced change of trigger index
- the triggers are normally increase only,
but can now override this optionally
Description
Function1 wrapper that maps the input value prior to it being used by
another Function1.
Example usage for limiting a polynomial:
\verbatim
<entryName>
{
type inputValueMapper;
mode minMax;
min 0.4;
max 1.4;
value polynomial
(
(5 1)
(-2 2)
(-2 3)
(1 4)
);
}
\endverbatim
Here the return value will be:
- poly(0.4) for x <= 0.4;
- poly(1.4) for x >= 1.4; and
- poly(x) for 0.4 < x < 1.4.
Example usage for supplying a patch mass flux for a table lookup:
\verbatim
<entryName>
{
type inputValueMapper;
mode function;
function
{
type functionObjectValue;
functionObject surfaceFieldValue1;
functionObjectResult sum(outlet,phi);
}
value
{
type table;
file "<system>/fanCurve.txt";
}
}
\endverbatim
Where:
\table
Property | Description | Required
mode | Mapping mode (see below) | yes
function | Mapping Function1 | no*
min | Minimum input value | no*
max | Maximum input value | no*
value | Function of type Function1<Type> | yes
\endtable
Mapping modes include
- none : the input value is simply passed to the 'value' Function1
- function : the input value is passed through the 'function' Function1
before being passed to the 'value' Function1
- minMax : limits the input value to 'min' and 'max' values before being
passed to the 'value' Function1
Note
Replaces the LimitRange Function1 (v2106 and earlier)
Returns a value retrieved from a function object result.
Usage:
<entryName> functionObjectValue;
<entryName>Coeffs
{
functionObject <name>;
functionObjectResult <function object result field name>
}
Function1 can now be created with an object registry, e.g. time or mesh
database. This enables access to other stored objects, e.g. fields,
dictionaries etc. making Function1 much more flexible.
Note: will allow TimeFunction1 to be deprecated
- additional debug information
- improve support for dictionary specification of constant, polynomial
and table entries. These previously only worked properly for
primitiveEntry, which causes confusion.
- extend table Function1 to include TableFile functionality.
Simplifies switching and modifying content.
- improves interface and data consistency.
Older signatures are still active (via the Foam_IOstream_extras
define).
- refine internals for IOstreamOption streamFormat, versionNumber
ENH: improve data alignment for IOstream and IOobject
- fit sizeof label/scalar into unsigned char
STYLE: remove dead code
- centralises existing functions (erfInv, incGamma*, invIncGamma*).
Provides a location for additional functions in the future.
- adjusted existing models to use these functions
(e.g. distributionModels::normal)
Function1 wrapper that limits the input range of another Function1
Example usage for limiting a polynomial:
limitedPolyTest limitRange;
limitedPolyTestCoeffs
{
min 0.4;
max 1.4;
value polynomial
(
(5 1)
(-2 2)
(-2 3)
(1 4)
);
}
Here the return value will be:
- poly(0.4) for x <= 0.4;
- poly(1.4) for x >= 1.4; and
- poly(x) for 0.4 < x < 1.4.
- For slow oscillations it can be more intuitive to specify the
period.
ENH: separate mark/space for Square
- makes it easier to tailor the desired intervals.
BUG: incorrect square wave fraction with negative phase shifts
ENH: additional cosine Function1
STYLE: avoid code duplication by inheriting Cosine/Square from Sine.
- easier support for non-mandatory functions.
In some boundary conditions it can be desirable to support
additional functions, but not necessarily require them. Make this
easier to support with a Function1, PatchFunction1 NewIfPresent()
selector.
- support for compatibility lookups
- harmonize branching logic and error handling between Function1 and
PatchFunction1.
ENH: refactor a base class for Function1, PatchFunction1
- includes base characteristics, patch or scalar information
ENH: additional creation macros
- makeConcreteFunction1, makeConcretePatchFunction1Type for adding a
non-templated function into the correct templated selection table.
makeScalarPatchFunction1 for similarity with makeScalarFunction1
- slipped in with changes to csvTableReader (commit 59ed3ba18d) so
only affects the 2006 version.
- adjust constructor to expect "componentColumns", but also accept
"valueColumns" as 1912 and earlier-compatibility. This not only
fixes the reported bug, but also ensure proper compatibility with
older files.
ENH: use "refColumn" instead of "timeColumn" for csvTableReader
- consistent with the CSV Function1.
Support 'timeColumn' as 1912 and earlier-compatibility.
TUT: remove unused table-reader entry
