If the solver use psiThermo rho = p*psi. If p < 0 then rho < 0 and
consequently nu < 0. This happens for steady solvers such as rhoSimpleFoam.
Adding limiters to laminar nu.
fvOptions are transferred to the database on construction using
fv::options::New which returns a reference. The same function can be
use for construction and lookup so that fvOptions are now entirely
demand-driven.
The abstract base-classes for fvOptions now reside in the finiteVolume
library simplifying compilation and linkage. The concrete
implementations of fvOptions are still in the single monolithic
fvOptions library but in the future this will be separated into smaller
libraries based on application area which may be linked at run-time in
the same manner as functionObjects.
Moved correctNut call from constructors to the new validate function to
avoid problems with construction order and field availability for the
calculation of nut.
To ensure nut is physical and consistent with the turbulence fields the
validate function should be called after the construction of the
turbulence model, fvOptions and any other fields that the calculation of
nut might depend on.

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
This bc was in compressible turbulence library which made it dependent
on liquidProperties. It was moved to a separate library since it is only
used in a single tutorial.
