    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;
            }
        }
