- prior to sampledSurface supporting different interpolation schemes a
workaround means was used to simulate cellPoint -> face
interpolation, with averaging of vertex interpolation.
We instead now use cellPoint interpolation directly for the face
values when 'interpolate=true'.
- fits better into the general sampling framework, improves flexibilty
and allows code reduction.
ENH: include surface fields on sampledSurfaces that support it
- The writers have changed from being a generic state-less set of
routines to more properly conforming to the normal notion of a writer.
These changes allow us to combine output fields (eg, in a single
VTK/vtp file for each timestep).
Parallel data reduction and any associated bookkeeping is now part
of the surface writers.
This improves their re-usability and avoids unnecessary
and premature data reduction at the sampling stage.
It is now possible to have different output formats on a per-surface
basis.
- A new feature of the surface sampling is the ability to "store" the
sampled surfaces and fields onto a registry for reuse by other
function objects.
Additionally, the "store" can be triggered at the execution phase
as well
- more dictionary-like methods, enforce keyType::LITERAL for all
lookups to avoid any spurious keyword matching.
- new readEntry, readIfPresent methods
- The get() method replaces the now deprecate lookup() method.
- Deprecate lookupOrFailsafe()
Failsafe behaviour is now an optional parameter for lookupOrDefault,
which makes it easier to tailor behaviour at runtime.
- output of the names is now always flatted without line-breaks.
Thus,
os << flatOutput(someEnumNames.names()) << nl;
os << someEnumNames << nl;
both generate the same output.
- Constructor now uses C-string (const char*) directly instead of
Foam::word in its initializer_list.
- Remove special enum + initializer_list constructor form since
it can create unbounded lookup indices.
- Removd old hasEnum, hasName forms that were provided during initial
transition from NamedEnum.
- Added static_assert on Enum contents to restrict to enum or
integral values. Should not likely be using this class to enumerate
other things since it internally uses an 'int' for its values.
Changed volumeType accordingly to enumerate on its type (enum),
not the class itself.
- improvement documentation for surface sampling.
- can now specify alternative sampling scheme for obtaining the
face values instead of just using the "cell" value. For example,
sampleScheme cellPoint;
This can be useful for cases when the surface is close to a boundary
cell and there are large gradients in the sampled field.
- distanceSurface now handles non-closed surfaces more robustly.
Unknown regions (not inside or outside) are marked internally and
excluded from consideration. This allows use of 'signed' surfaces
where not previously possible.
"pos" now returns 1 if the argument is greater than 0, otherwise it returns 0.
This is consistent with the common mathematical definition of the "pos" function:
https://en.wikipedia.org/wiki/Sign_(mathematics)
However the previous implementation in which 1 was also returned for a 0
argument is useful in many situations so the "pos0" has been added which returns
1 if the argument is greater or equal to 0. Additionally the "neg0" has been
added which returns 1 if if the argument is less than or equal to 0.
- affects surfaceFieldValue, volFieldValue.
Use 'none' (if desired) to explicitly suppress the weightField, but
generally better to use a different operation.
- can be useful either for flow-rate weighting where backflow
is to be ignored in the average, or for flow-rate weighting
on surfaces with inconsistent orientation.
Reworked to code to make better use of Enum (the NamedEnum
replacement). Enum doesn't require contiguous enumeration values,
which lets us use bitmasking of similar operations to reduce
duplicate code.
- Remove the unused enums() method since it delivers wholly unreliable
results. It is not guaranteed to cover the full enumeration range,
but only the listed names.
- Remove the unused strings() method.
Duplicated functionality of the words(), but was never used.
- Change access of words() method from static to object.
Better code isolation. Permits the constructor to take over
as the single point of failure for bad input.
- Add values() method
- do not expose internal (HashTable) lookup since it makes it more
difficult to enforce constness and the implementation detail should
not be exposed. However leave toc() and sortedToc() for the interface.
STYLE: relocated NamedEnum under primitives (was containers)
- internal typedef as 'value_type' for some consistency with STL conventions
- this makes it possible to perform additional operations
on surface values that have been previously sampled.
- support vectorField for weighting operations.
- reduce overhead by avoiding creation of weight fields, Sf fields
and combined surface geometries unless they are actually required.
- extend some similar concepts and operations to volFieldValue
- Allows passing of additional information (per-face zone ids) or possibly
other things, while reducing the number of arguments to pass.
- In sampledTriSurfaceMesh, preserve the region information that was
read in, passing it onwards via the UnsortedMeshSurface content.
The Nastran surface writer is currently the only writer making use
of this per-face zone information.
Passing it through as a PSHELL attribute, which should retain the
distinction for parts. (issue #204)
