Description
Allows specification of different writing frequency of objects registered
to the database.
It has similar functionality as the main time database through the
\c writeControl setting:
- timeStep
- writeTime
- adjustableRunTime
- runTime
- clockTime
- cpuTime
It also has the ability to write the selected objects that were defined
with the respective write mode for the requested \c writeOption, namely:
- \c autoWrite - objects set to write at output time
- \c noWrite - objects set to not write by default
- \c anyWrite - any option of the previous two
Example of function object specification:
\verbatim
writeObjects1
{
type writeObjects;
libs ("libutilityFunctionObjects.so");
...
objects (obj1 obj2);
writeOption anyWrite;
}
\endverbatim

Resolves bug-report http://bugs.openfoam.org/view.php?id=2090
Time: call functionObject 'execute()' and 'end()' for last time-step
Now the operation of functionObject 'end()' call is consistent between running and post-processing
Now the number of iterations to solve each component in a segregated
solution are stored and returned in the SolverPerformance class.

This was going wrong in a fair few cases where you would get regions which
were delimited by a combination of intersections with unnamed surfaces (wall)
and named surfaces (faceZone surface) but not with either of these sets
individually. This would cause there to be unvisited cells (zone = -2)
next to a visited cells but separated by a named surface only (and not an
unnamed surface). Fixed by using direct surface intersection in the removal
part. Related to #66.
Note that since these actually act more like 'patches'
(ie, contiguous addressing) it might be reasonable to rename as
surfPatchIdentifier / surfacePatchIdentifier
- Now that the metisDecomp uses the metis definition for float/double,
do not need to verify the scalar sizes.
Note:
- could drop precision qualifier for metis, scotch installation
(include, lib) as being unneeded, but it is simpler to keep them
and continue to use the FOAM_EXT_LIBBIN path
(in case other ThirdParty software is compiled with different
precisions).
- Cannot pass through to underlying list constructor directly.
- As this constructor was broken, there seem to be a number of
workarounds scattered in the code. Could revisit them in the future
as part of code-style:
edgeMesh(const Xfer<pointField>&, const Xfer<edgeList>&);
CompactIOField(const IOobject&, const Xfer<Field<T>>&);
GlobalIOField(const IOobject&, const Xfer<Field<Type>>&);
IOField(const IOobject&, const Xfer<Field<Type>>&);
- Condition is there to catch cases where the vtkSurfaceFormat returns
no zones (which should never be the case), but assigns a fallback
value without first resizing.
- This format is fortunately little-used (or never used) since its
inception.
Using raw stream operators to write zones, points and faces in a
single file was not well thought out - the output content varies
with the Face template type (face, triFace, labelledFace), which
makes it not very robust at all.
The static read in OFSsurfaceFormat also has a bug - keeping
transcribed faces from being passed through.
Conclusion: removing it makes more sense that repairing and still
not having something good.
Do retain stream operators for MeshedSurface and UnsortedMeshedSurface,
since they are useful for passing around data
(eg, between processors), but they shouldn't be used for files.
Note: classes are prefixed with 'foamVtk' instead of 'vtk' to avoid potential
conflicts with VTK itself.
foamVtkCore
~~~~~~~~~~~
- General very low-level functionality.
foamVtkPTraits
~~~~~~~~~~~~~~
- Traits type of functionality for VTK
foamVtkOutputOptions
~~~~~~~~~~~~~~~~~~~~
- The various format output options as a class that can be passed to
formatters etc.
foamVtkCells
~~~~~~~~~~~~
- Intended for unifying vtkTopo and PV-Reader code in the future.
- Handles polyhedron decompose internally etc
foamVtkOutput, foamVtkFormatter
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- Output helpers.
- Selector for individual formatters.
Currently write all scalar data a 'float' (not 'double'). Can
revisit this in the future.
