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.

- To use the new convection scheme, add the library
libturbulenceModelSchemes.so to the $FOAM_CASE controlDict
The old version of regionSplit would hand out regions one by one. This
is a big problem when there are lots of regions - the extreme being
in the decompositionMethods, where it is used to cluster cells and most clusters
being only one cell. This rewrite uses a mesh wave to determine disconnected
regions in one go. This produced non-compact numbering which is then compacted
in a second phase.
On a 14M cell case with cyclic constraints this reduced decompose
time from 40 mins down to 5.
Before was zeroing displacement on all coupled points before
applying the displacement. This meant that we could not modify the
internal displacement on coupled points before setting the patch displacement.
Fixes#10.
- moved control to functionObject (from bc)
- this allows multi-region support
- see heatTransfer/chtMultiRegionFoam/externalCoupledMultiRegionHeater tut
- generalisation of streamed reading/writing of specialised bcs
ENH: Foam abort - reading from env(FOAM_ABORT) instead of caching value on construction
As discussed - no longer caching value of FOAM_ABORT on construction of error class; instead, always read from FOAM_ABORT. Should be no perceived performance impact since this is only triggered on exit/abort.

Feature function objects
Lots of code migrated from internal development line, code tidying and a few fixes
Updated objects
- corrected Peclet number for compressible cases
- propagated log flag and resultName across objects
New function objects
- new fluxSummary:
- calculates positive, negative, absolute and net flux across face
zones
- new runTimeControl
- abort the calculation when a user-defined metric is achieved.
Available options include:
- average value remains unchanged wrt a given threshold
- equation initial residual exceeds a threshold - useful to abort
diverging cases
- equation max iterations exceeds a threshold - useful to abort
diverging cases
- min/max of a function object value
- min time step exceeds a threshold - useful to abort diverging
cases
- new valueAverage:
- average singular values from other function objects, e.g. Cd, Cl and
Cm from the forceCoeffs function object
