Rather than requiring each functionObject to handle failed construction
internally (using the active_ flag) the static member function "viable"
is provided which returns true if construction of the functionObject is
likely to be successful. Failed construction is then handled by the
wrapper-class which constructs the functionObject,
e.g. "OutputFilterFunctionObject".
These new names are more consistent and logical because:
primitiveField():
primitiveFieldRef():
Provides low-level access to the Field<Type> (primitive field)
without dimension or mesh-consistency checking. This should only be
used in the low-level functions where dimensional consistency is
ensured by careful programming and computational efficiency is
paramount.
internalField():
internalFieldRef():
Provides access to the DimensionedField<Type, GeoMesh> of values on
the internal mesh-type for which the GeometricField is defined and
supports dimension and checking and mesh-consistency checking.
When the GeometricBoundaryField template class was originally written it
was a separate class in the Foam namespace rather than a sub-class of
GeometricField as it is now. Without loss of clarity and simplifying
code which access the boundary field of GeometricFields it is better
that GeometricBoundaryField be renamed Boundary for consistency with the
new naming convention for the type of the dimensioned internal field:
Internal, see commit 4a57b9be2e
This is a very simple text substitution change which can be applied to
any code which compiles with the OpenFOAM-dev libraries.
The deprecated non-const tmp functionality is now on the compiler switch
NON_CONST_TMP which can be enabled by adding -DNON_CONST_TMP to EXE_INC
in the Make/options file. However, it is recommended to upgrade all
code to the new safer tmp by using the '.ref()' member function rather
than the non-const '()' dereference operator when non-const access to
the temporary object is required.
Please report any problems on Mantis.

When restarting form a previous calculation, the averaging is continuous or
may be restarted using the \c restartOnRestart option.
The averaging process may be restarted after each calculation output time
using the \c restartOnOutput option or restarted periodically using the \c
periodicRestart option and setting \c restartPeriod to the required
averaging period.
Example of function object specification:
\verbatim
fieldAverage1
{
type fieldAverage;
functionObjectLibs ("libfieldFunctionObjects.so");
...
restartOnRestart false;
restartOnOutput false;
periodicRestart false;
restartPeriod 0.002;
fields
(
U
{
mean on;
prime2Mean on;
base time;
window 10.0;
windowName w1;
}
p
{
mean on;
prime2Mean on;
base time;
}
);
}
\endverbatim

This had been used in functionObjects:
Info(log)<< "messages" << data << ....
in which it is not at all clear what the "log" argument does whereas
if (log) Info<< "messages" << data << ....
is totally clear and more efficient.
Previous behavior which may be useful for moving-mesh cases can be
selected using the optional entry:
writeVolume yes;
The initial volume is written in the log and data file header e.g.:
# Source : all
# Cells : 3829
# Volume : 9.943164e-01
Also added
sumMag | sum of component magnitudes
Previous behavior which may be useful for moving-mesh cases can be
selected using the optional entry:
writeTotalArea yes;
The initial total area is written in the log and data file header e.g.:
# Source : faceZone f0
# Faces : 8
# Area : 1.063860e-02
