- added constructor dictionary(const dictionary*) that also handles NULL
pointers and makes it convenient to construct from a possibly nonexistent
sub-dictionary:
eg,
dictionary dict2(dict1.subDictPtr("someDict"));
- make some of the turbulence Coeffs sub-dictionary optional.
Their contents are all 'lookupOrAddDefault' anyhow.
- in turbulentMixingLength BCs, skip namespace qualifier in template
(eg, <RASModel> vs. <compressible::RASModel>)
- change comments from 'turbulenceProperties' to RASProperties/LESProperties
- consistency between compressible/incompressible - no separate file for
'New' selector etc
- consistency in accessing the model coefficients.
Use method coeffDict() for const access.
Use protected data member coeffDict_ for read/write access.
- document model coefficients in etc/constant/RASProperties.
Need the same for LESProperties before we can prune these from the
tutorials.
