9801c25788 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;
        }
    }

2eac40eac6 dynamicMotionSolverListFvMesh: New mesh-motion solver supporting multiple moving regions
e.g. the motion of two counter-rotating AMI regions could be defined:

dynamicFvMesh   dynamicMotionSolverListFvMesh;

solvers
(
    rotor1
    {
        solver solidBody;

        cellZone        rotor1;

        solidBodyMotionFunction  rotatingMotion;
        rotatingMotionCoeffs
        {
            origin        (0 0 0);
            axis          (0 0 1);
            omega         6.2832; // rad/s
        }
    }

    rotor2
    {
        solver solidBody;

        cellZone        rotor2;

        solidBodyMotionFunction  rotatingMotion;
        rotatingMotionCoeffs
        {
            origin        (0 0 0);
            axis          (0 0 1);
            omega         -6.2832; // rad/s
        }
    }
);

Any combination of motion solvers may be selected but there is no special
handling of motion interaction; the motions are applied sequentially and
potentially cumulatively.

To support this new general framework the solidBodyMotionFvMesh and
multiSolidBodyMotionFvMesh dynamicFvMeshes have been converted into the
corresponding motionSolvers solidBody and multiSolidBody and the tutorials
updated to reflect this change e.g. the motion in the mixerVesselAMI2D tutorial
is now defined thus:

dynamicFvMesh   dynamicMotionSolverFvMesh;

solver solidBody;

solidBodyCoeffs
{
    cellZone        rotor;

    solidBodyMotionFunction  rotatingMotion;
    rotatingMotionCoeffs
    {
        origin        (0 0 0);
        axis          (0 0 1);
        omega         6.2832; // rad/s
    }
}
