The templates include a stategy to simplify meshing with snappyHexMesh,
particularly to help generate an initial mesh quickly that can subsequently be
improved.  The templates are setup to enable rapid initial simulations, typically
with simpleFoam.  The initial templates cover simple inflow-outflow and closed
domains, including rotating geometry, and an example axisymmetric flow.  For
more details, consult the README file accompanying each template case.
The cases are located in $FOAM_ETC/templates

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
