Usage

Example usage for mineral slurry:

    packingDispersionModel Usher;

    UsherCoeffs
    {
        alphaGel        0.1;
        alphap          0.8;
        alphacp         0.8;
        alphag          0;
        alphaMax        1;
        b1              2e-3;
        sigma01         3.18663;
        n1              11;
        b2              1;
    }
