- handle tmp fields in interpolate methods
- special method interpolateInternal() for creating a volume field
with zero-gradient treatment for patches from an internal field.
This method was previously also called interpolate(), but that
masked the ability to subset the internal field only.
Ensight output needs the volume field:
uses interpolateInternal().
VTK output has separate handling of internal and patch fields:
uses interpolate().
ENH: added fvMeshSubset mesh() method for baseMesh or subMesh.
- simplies coding when the fvMeshSubset may or may not be in active use.
ENH: update foamToEnsight to use newer methods in wrapped form
- static interpolate functions with renaming for manual use with
fvMeshSubset (when fvMeshSubsetProxy may be too limiting in
functionality)
General:
* -roots, -hostRoots, -fileHandler
Specific:
* -to <coordinateSystem> -from <coordinateSystem>
- Display -help-compat when compatibility or ignored options are available
STYLE: capitalization of options text
- relocated HashSetPlusEqOp and HashTablePlusEqOp to
HashSetOps::plusEqOp and HashTableOps::plusEqOp, respectively
- additional functions for converting between a labelHashSet
and a PackedBoolList or List<bool>:
From lists selections to labelHashSet indices:
HashSetOps::used(const PackedBoolList&);
HashSetOps::used(const UList<bool>&);
From labelHashSet to list forms:
PackedBoolList bitset(const labelHashSet&);
List<bool> bools(const labelHashSet&);
- this currently just strips off the leading parent directory name
"/this/path/and/subdirs/name"
relative("/this/path") -> "and/subdirs/name"
relative("/this") -> "path/and/subdirs/name"
- problems when the cloud was not available on all processors.
- NB: ensight measured data only allows a single cloud, but
foamToEnsight writes all clouds.
- use succincter method names that more closely resemble dictionary
and HashTable method names. This improves method name consistency
between classes and also requires less typing effort:
args.found(optName) vs. args.optionFound(optName)
args.readIfPresent(..) vs. args.optionReadIfPresent(..)
...
args.opt<scalar>(optName) vs. args.optionRead<scalar>(optName)
args.read<scalar>(index) vs. args.argRead<scalar>(index)
- the older method names forms have been retained for code compatibility,
but are now deprecated
old "positions" file form
The change to barycentric-based tracking changed the contents of the
cloud "positions" file to a new format comprising the barycentric
co-ordinates and other cell position-based info. This broke
backwards compatibility, providing no option to restart old cases
(v1706 and earlier), and caused difficulties for dependent code, e.g.
for post-processing utilities that could only infer the contents only
after reading.
The barycentric position info is now written to a file called
"coordinates" with provision to restart old cases for which only the
"positions" file is available. Related utilities, e.g. for parallel
running and data conversion have been updated to be able to support both
file types.
To write the "positions" file by default, use set the following option
in the InfoSwitches section of the controlDict:
writeLagrangianPositions 1;
- erroneous double logic for subset meshes.
The underlying vtk::vtuCells uses a cellMap to map into a global
field, which also allows handling of decomposed polyhedral cells.
If a mesh subset is involved (eg, cellSet, cellZone), then the
set/zone cellMap can be used to ensure that the original number is
properly adjusted. For foamToVTK, the meshSubsetHelper already
does the subsetting and is used when loading fields.
Does not affect ParaView reader module since there we work on the
full field and do the subsetting manually (using the cellMap).
- with the xml append format it is possible to write raw binary
(instead of base64), but the writer becomes more complicated.
Either needs two passes to create, or need to allocate a block
of space for the header information (like VTK itself does) and
write later.
* internalWriter
* patchWriter
* surfaceMeshWriter
* lagrangianWriter
Also these special purpose ones:
* foamVtkWriteSurfFields
- this shifts responsibility away from caller to the individual writers
for knowing which file formats are supported and which file ending is
appropriate. When the writer receives the output format request,
it can elect to downgrade or otherwise adjust it to what it can
actually manage (eg, legacy vs xml vs xml-append).
But currently still just with legacy format backends.
- ensure that the string-related classes have consistently similar
matching methods. Use operator()(const std::string) as an entry
point for the match() method, which makes it easier to use for
filters and predicates. In some cases this will also permit using
a HashSet as a match predicate.
regExp
====
- the set method now returns a bool to signal that the requested
pattern was compiled.
wordRe
====
- have separate constructors with the compilation option (was previously
a default parameter). This leaves the single parameter constructor
explicit, but the two parameter version is now non-explicit, which
makes it easier to use when building lists.
- renamed compile-option from REGEX (to REGEXP) for consistency with
with the <regex.h>, <regex> header names etc.
wordRes
====
- renamed from wordReListMatcher -> wordRes. For reduced typing and
since it behaves as an entity only slightly related to its underlying
list nature.
- Provide old name as typedef and include for code transition.
- pass through some list methods into wordRes
hashedWordList
====
- hashedWordList[const word& name] now returns a -1 if the name is is
not found in the list of indices. That has been a pending change
ever since hashedWordList was generalized out of speciesTable
(Oct-2010).
- add operator()(const word& name) for easy use as a predicate
STYLE: adjust parameter names in stringListOps
- reflect if the parameter is being used as a primary matcher, or the
matcher will be derived from the parameter.
For example,
(const char* re), which first creates a regExp
versus (const regExp& matcher) which is used directly.
The normal library system() command uses 'fork', which causes
problems on IB+OPENMPI.
STYLE: add Foam:: qualifier to system calls to make them easier to spot.
Description
This functionObject writes objects registered to the database in VTK format
using the foamToVTK library.
Currently only the writing of the cell-values of volFields is supported but
support for other field types, patch fields, Lagrangian data etc. will be
added.
Example of function object specification:
\verbatim
writeVTK1
{
type writeVTK;
functionObjectLibs ("libIOFunctionObjects.so");
...
objectNames (obj1 obj2);
}
\endverbatim
