Many possibilities:
- use as a simple calculator with vectors, tensors etc.
- test validity of expression syntax

As a calculator:

    foamCalc  '(vector(1,2,3) ^ vector(4,5,6)) * sqrt(34)'

The same, but with debugging:

    foamCalc -debug-switch fieldExpr=6 \
        'mag((vector(1,2,3) ^ vector(4,5,6))) * sqrt(34)'

- previously just reported gcc/clang versions, but these are not
  necessarily the ones actually being used (eg, clang-9 vs clang).
  Now use the path from `wmake -show-path-cxx` to improve the accuracy,
  and also support other compiler types.

- now use debug 2 for scanner and debug 4 for parser.
  Provided better feedback about what is being parsed (debug mode)

- relocate debug application to applications/tools/foamExprParserInfo

New VOF multiphaseStabilizedTurbulence fvOption

See merge request !316

Andrew Heather authored Dec 10, 2019 and Andrew Heather committed Dec 19, 2019

See GL #1433

Applies corrections to turbulence kinetic energy equation and turbulence
viscosity field for incompressible multiphase flow cases.

Turbulence kinetic energy is over-predicted in VOF solvers at the phase
interface and throughout the water column in nearly-potential flow regions
beneath surface waves.

This fvOption applies corrections based on the references:

    Buoyancy source term in turbulence kinetic energy equation:

        Devolder, B., Rauwoens, P., and Troch, P. (2017).
        Application of a buoyancy-modified k-w SST turbulence model to
        simulate wave run-up around a monopile subjected to regular waves
        using OpenFOAM.
        Coastal Engineering, 125, 81-94.

    Correction to turbulence viscosity field:

        Larsen, B.E. and Fuhrman, D.R. (2018).

        Reynolds-averaged Navier-Stokes models

    ENH: modify fWallFunction for kEpsilonPhitF model

    The k-epsilon-phit-f turbulence closure model for incompressible and
    compressible flows.

    The model is a three-transport-equation linear-eddy-viscosity turbulence
    closure model alongside an elliptic relaxation equation:
      - Turbulent kinetic energy, \c k,
      - Turbulent kinetic energy dissipation rate, \c epsilon,
      - Normalised wall-normal fluctuating velocity scale, \c phit,
      - Elliptic relaxation factor, \c f.

Note
    The name of the original variable replacing 'v2' is 'phi' (LUU:Eq. 14).
    However, the name 'phi' preexisted in OpenFOAM; therefore, this name was
    replaced by 'phit'

qem and qin were not set to zero for the wideBand model BC.
qin was used in the grey model BC to calculate Ir(the total
incoming heat flux). As it is now set to zero, the grey model
loops over the incoming rays to calculate Ir instead of relaying
on qin stored in radiativeIntensityRay.
