1) PhaseIncompressibleTurbulenceModel class was changed to use
uniform alpha and non-uniform rho templates. This fits the need
of incompressible two phase turbulence models.
2) A new type DPMIncompressibleTurbulenceModel was created for
non-uniform alpha and uniform rho. It is used in single phase flows
in DPM solvers where alpha represents the volumen occupancy.
3) A new type incompressibleRhoTurbulenceModel was created where
non-uniform rho is allowed.
4) A new base templated turbulent class for two-phase VOF named
VoFphaseTurbulentTransportModel was implemented which is created
templating on PhaseIncompressibleTurbulenceModel and
incompressibleRhoTurbulenceModel
5) In order to make the chnage to rho based VOF turbulence a help
class was added incompressibleInterPhaseTransportModel templated
on the mixing.
Within decomposeParDict, it is now possible to specify a different
decomposition method, methods coefficients or number of subdomains
for each region individually.
The top-level numberOfSubdomains remains mandatory, since this
specifies the number of domains for the entire simulation.
The individual regions may use the same number or fewer domains.
Any optional method coefficients can be specified in a general
"coeffs" entry or a method-specific one, eg "metisCoeffs".
For multiLevel, only the method-specific "multiLevelCoeffs" dictionary
is used, and is also mandatory.
----
ENH: shortcut specification for multiLevel.
In addition to the longer dictionary form, it is also possible to
use a shorter notation for multiLevel decomposition when the same
decomposition method applies to each level.
- although this has been supported for many years, the tutorials
continued to use "convertToMeters" entry, which is specific to blockMesh.
The "scale" is more consistent with other dictionaries.
ENH:
- ignore "scale 0;" (treat as no scaling) for blockMeshDict,
consistent with use elsewhere.
- Use on/off vs longer compressed/uncompressed.
For consistency, replaced yes/no with on/off.
- Avoid the combination of binary/compressed,
which is disallowed and provokes a warning anyhow
