Detailed Description

Evolves a passive scalar transport equation.

- To specify the field name set the field entry

To employ the same numerical schemes as another field set the schemesField entry,
The diffusivity entry can be set to none, constant, viscosity
A constant diffusivity is specified with the D entry,
If a momentum transport model is available and the viscosity diffusivity option specified an effective diffusivity may be constructed from the laminar and turbulent viscosities using the diffusivity coefficients alphal and alphat:
```
      D = alphal*nu + alphat*nut
```

Example:

    #includeFunc scalarTransport(T, alphal=1, alphat=1)

For incompressible flow the passive scalar may optionally be solved with the MULES limiter and sub-cycling or semi-implicit in order to maintain boundedness, particularly if a compressive, PLIC or MPLIC convection scheme is used.

Example:

    #includeFunc scalarTransport(tracer, diffusion=none)

with scheme specification:
    div(phi,tracer)     Gauss interfaceCompression vanLeer 1;

and solver specification:
    tracer
    {
        nCorr      1;
        nSubCycles 3;

        MULESCorr       no;
        nLimiterIter    5;
        applyPrevCorr   yes;

        solver          smoothSolver;
        smoother        symGaussSeidel;
        tolerance       1e-8;
        relTol          0;

        diffusion
        {
            solver          smoothSolver;
            smoother        symGaussSeidel;
            tolerance       1e-8;
            relTol          0;
        }
    }
