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

for more convenient case setup

See $FOAM_ETC/caseDicts/postProcessing/README for details

Note that in order to build and install ParaView-4.3.1 lines 653-656
must be removed or commented from file

ThirdParty-dev/ParaView-4.3.1/Qt/Components/CMakeLists.txt

after unpacking the ParaView-4.3.1 source-pack from KitWare.  This is
because the file ui_pqExportStateWizard.h referred to in the lines
653-656:

if(PARAVIEW_INSTALL_DEVELOPMENT_FILES)
  install(FILES "${CMAKE_CURRENT_BINARY_DIR}/ui_pqExportStateWizard.h"
          DESTINATION "${VTK_INSTALL_INCLUDE_DIR}")
endif()

does not exist and cannot be installed causing the build and
installation to fail.

Currently timeStampMaster does not support re-reading of IOdictionaries in parallel

When using models which require the wallDist e.g. kOmegaSST it will
request the method to be used from the wallDist sub-dictionary in
fvSchemes e.g.

wallDist
{
    method meshWave;
}

specifies the mesh-wave method as hard-coded in previous OpenFOAM versions.

Added InfoSwitches::writeOptionalEntries which enables the writing of optional keywords and values which are not present in the dictionary
Warning: generates a VERY large number of messages from OpenFOAM applications

To compile with 64bit labels set

WM_LABEL_SIZE=64

in ~/OpenFOAM/dev/prefs.sh

source ~/.bashrc

then Allwmake in OpenFOAM-dev.

This will build into for example OpenFOAM-dev/platforms/linux64ClangDPInt64Opt

If WM_LABEL_SIZE is unset or set to 32:

WM_LABEL_SIZE=32

the build would be placed into OpenFOAM-dev/platforms/linux64ClangDPInt32Opt

Thus both 32bit and 64bit label builds can coexist without problem.
