- old convention was that on last time step it would only call end()
and not execute()
- however this meant that e.g. the functionObjectProperties file
did not get written
- and almost all functionObjects were doing an execute() inside of end()
- new convention: call execute() on last time step, just before doing end()

Feature turbulence

Integration of new kOmega SST turbulence model variants: DES, DDES, IDDES

Initially supplied by CFD Software E+F GmbH



See merge request !20

ENH: Added new ceeateZeroDirectory utility

Uses a system/caseProperties file to select templates from
etc/caseDicts/createZeroDirectoryTemplates to enable high-level setup
of a case.
See
- etc/caseDicts/createZeroDirectoryTemplates
- tutorials/preProcessing/createZeroDirectory

See merge request !19

- Initial code supplied by CFD Software E+F GmbH
- Refactored and integrated into the new templated Turbulence structure
  by OpenCFD

It was not correctly interpolating faceZones which are on processor boundaries.
This caused difference between serial and parallel running. Fixes #16.

Included option to use the low Reynolds number correction, with a
default value of 'on'.  Further details can be found in the reference:

    A new version of detached-eddy simulation, resistant to ambiguous grid
    densities.
    Theor. Comput. Fluid Dyn., 20, 181-195.

Set using the entry:

    lowReCorrection on; // off

Some bcs (e.g. humidity) use an external transported field so this needs
to be registered asap.

ENH: foamHelp - added support for solvers

- Added support for solvers
- Updated use of FOAM_ABORT - old code left commented in helpBoundary.C for now...

Feature turbulence

Turbulence updates from our internal development line:
- Added DESModel base class for DES models
- Moved DES models to separate DES directory
- Added DESModelRegions function object
- Updated porousBafflePressure BC to use DataEntry class for D and I inputs
- Documentation updates

See merge request !17

For distributed data + running redistributePar some of the processors
might not have level0Edge. In this case the sync() routine should
fix this but it does require at least the master to have valid data.

- Initial code supplied by CFD Software E+F GmbH
- Refactored and integrated into the new templated Turbulence structure by
  OpenCFD
- To use the new convection scheme, add the library
  libturbulenceModelSchemes.so to the $FOAM_CASE controlDict

Object generates an indicator field for DES turbulence models to show
in which regions LES or RAS modelling is active.

SpalartAllmarasDES now derived from DESModel class

The signal handling can now be set and unset. This latter is important
for external libraries (e.g. VTK/OpenGL) that do not work with it.
