With this change each functionObject provides the list of fields required so
that the postProcess utility can pre-load them before executing the list of
functionObjects. This provides a more convenient interface than using the
-field or -fields command-line options to postProcess which are now redundant.
This avoids attempting to write temporary fields before they have been created.
The executeAtStart can be set to 'yes' in the writeObjects dictionary or the
functions
{
#includeFunc writeObjects(executeAtStart = yes, <field1>, <field2>...)
}
This is a slight modification of the previous commit. All cached
temporary fields are now written to disk with the name enclosed by
"tmp<...>". This still allows for automatically constructed
field names to be read by paraFoam and other post-processing tools. It
also creates a consistent convention for naming all cached temporary
fields that are written to disk.
for example
cacheTemporaryObjects
(
"((1|((1|(1|A(U)))-H(1)))-(1|A(U)))"
);
functions
{
#includeFunc writeObjects(regExp=off, "((1|((1|(1|A(U)))-H(1)))-(1|A(U)))")
}
writes the temporary field with the name
"expr((1|((1|(1|A(U)))-H(1)))-(1|A(U)))" so that it can be read by paraFoam and
other post-processing tools.
When selecting fields with complex automatically generated names it is
cumbersome to escape all the regular expression meta characters and more
convenient to specify the name as a literal string, the new regExp option
provides the ability to switch the regular expression support and defaults to
true for backward compatibility.
For example to cache and write out an intermediate temporary field generated by
the kOmegaSST model:
cacheTemporaryObjects
(
"((interpolate(((1|((1|(1|A(U)))-H(1)))-(1|A(U))))*snGrad(p))*magSf)"
);
functions
{
#includeFunc writeObjects(regExp=off, "((interpolate(((1|((1|(1|A(U)))-H(1)))-(1|A(U))))*snGrad(p))*magSf)")
}
The regExp option can also be specified in a writeObjects dict as
regExp off;
Additionally regular expression support has been added to the includeFunc
argument parsing.
Currently these deleted function declarations are still in the private section
of the class declarations but will be moved by hand to the public section over
time as this is too complex to automate reliably.
defined by functionObjects, e.g. wallHeatFlux, wallShearStress and yPlus.

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

Replaced the 'postProcess' argument to the 'write' and 'execute'
functions with the single static member 'postProcess' in the
functionObject base-class.
