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.

Avoids duplicate typedefs.

for more convenient case setup

See $FOAM_ETC/caseDicts/postProcessing/README for details

For vector/tensor fields, e.g. U, the largest residual of all components is written out

On 32bit OSs long is not unambiguously int32_t (or int64_t) causing
problems for IO operator resolution.  This problem is avoided by
explicitly defining the following operators:

e.g. data files written by functionObjects
Attempts to interpret automatically the format of time-data files
Works successfully with majority of time-data output, e.g. forceCoeffs,
but will be unsuccesful on files with inconsistent output format

Creates symbolic links to all VTK files in a post-processing directory
Links form a sequence like name.0000.vtk, name.0001.vtk, etc.
Paraview recognises link names as a sequence which can be animated.
The sequence of links can be used to create a video from the images.

Time directory is first time directory (0) by default
Alternatively the user can specify the latest time directory
Requires the latest (2.3.x) foamListTimes utility

Treact: Temperature below which the reaction rates are assumed 0

to improve stability of the thermal system

If -rm is specified with the -processor option the selected time
directories are removed from all the processor directories.

patchInjection accumulates mass exchanges on a per-patch basis which are
reported by injectionModelList

twoPhaseEulerFoam: Update only the fixed-value phi patch fields before constructing the pressure eqn
Avoids small continuity error in parallel
