5c51836501 The "<type>Coeffs" sub-dictionary is now optional for most model parameters
except turbulence and lagrangian which will also be updated shortly.

For example in the nonNewtonianIcoFoam offsetCylinder tutorial the viscosity
model coefficients may be specified in the corresponding "<type>Coeffs"
sub-dictionary:

transportModel  CrossPowerLaw;

CrossPowerLawCoeffs
{
    nu0         [0 2 -1 0 0 0 0]  0.01;
    nuInf       [0 2 -1 0 0 0 0]  10;
    m           [0 0 1 0 0 0 0]   0.4;
    n           [0 0 0 0 0 0 0]   3;
}

BirdCarreauCoeffs
{
    nu0         [0 2 -1 0 0 0 0]  1e-06;
    nuInf       [0 2 -1 0 0 0 0]  1e-06;
    k           [0 0 1 0 0 0 0]   0;
    n           [0 0 0 0 0 0 0]   1;
}

which allows a quick change between models, or using the simpler

transportModel  CrossPowerLaw;

nu0         [0 2 -1 0 0 0 0]  0.01;
nuInf       [0 2 -1 0 0 0 0]  10;
m           [0 0 1 0 0 0 0]   0.4;
n           [0 0 0 0 0 0 0]   3;

if quick switching between models is not required.

To support this more convenient parameter specification the inconsistent
specification of seedSampleSet in the streamLine and wallBoundedStreamLine
functionObjects had to be corrected from

    // Seeding method.
    seedSampleSet   uniform;  //cloud; //triSurfaceMeshPointSet;

    uniformCoeffs
    {
        type        uniform;
        axis        x;  //distance;

        // Note: tracks slightly offset so as not to be on a face
        start       (-1.001 -0.05 0.0011);
        end         (-1.001 -0.05 1.0011);
        nPoints     20;
    }

to the simpler

    // Seeding method.
    seedSampleSet
    {
        type        uniform;
        axis        x;  //distance;

        // Note: tracks slightly offset so as not to be on a face
        start       (-1.001 -0.05 0.0011);
        end         (-1.001 -0.05 1.0011);
        nPoints     20;
    }

which also support the "<type>Coeffs" form

    // Seeding method.
    seedSampleSet
    {
        type        uniform;

        uniformCoeffs
        {
            axis        x;  //distance;

            // Note: tracks slightly offset so as not to be on a face
            start       (-1.001 -0.05 0.0011);
            end         (-1.001 -0.05 1.0011);
            nPoints     20;
        }
    }

ce0cd35185 Patches contributed by Mattijs Janssens:
splitMeshRegions: handle flipping of faces for surface fields

subsetMesh: subset dimensionedFields

decomposePar: use run-time selection of decomposition constraints. Used to
    keep cells on particular processors. See the decomposeParDict in

$FOAM_UTILITIES/parallel/decomposePar:
  - preserveBaffles: keep baffle faces on same processor
  - preserveFaceZones: keep faceZones owner and neighbour on same processor
  - preservePatches: keep owner and neighbour on same processor. Note: not
    suitable for cyclicAMI since these are not coupled on the patch level
  - singleProcessorFaceSets: keep complete faceSet on a single processor
  - refinementHistory: keep cells originating from a single cell on the
    same processor.

decomposePar: clean up decomposition of refinement data from snappyHexMesh

reconstructPar: reconstruct refinement data (refineHexMesh, snappyHexMesh)

reconstructParMesh: reconstruct refinement data (refineHexMesh, snappyHexMesh)

redistributePar:
  - corrected mapping surfaceFields
  - adding processor patches in order consistent with decomposePar

argList: check that slaves are running same version as master

fvMeshSubset: move to dynamicMesh library

fvMeshDistribute:
  - support for mapping dimensionedFields
  - corrected mapping of surfaceFields

parallel routines: allow parallel running on single processor

Field: support for
  - distributed mapping
  - mapping with flipping

mapDistribute: support for flipping

AMIInterpolation: avoid constructing localPoints
