constantScatterCFDEM

Description

The constantScatterCFDEM calculates the scattering coefficients and provides the field to the radiation model. (ie. P1CFDEM).

Syntax

scatterModel     constantScatterCFDEM;

constantScatterCFDEMCoeffs
{
    sigma        <scalar>;
    C            <scalar>;
    useParticleScatteringCoefficient <bool>;
    ScatteringCoeffFieldName         <word>;

}

sigma = scattering coefficient sigma
C = linear anisotropic phase function coefficient. Scalar value between -1 and 1, with C = 0 meaning isotropic scattering, C < 0 meaning backward scattering, and C > 0 forward scattering (default: 0, i.e. isotroic scattering)

The model calculates the scattering coefficient $\sigma_\mathrm{eff} = (3 - C) \sigma$ from the user-defined parameters.

Examples

Default use of the constantScatterCFDEM model:

scatterModel    constantScatterCFDEM;

constantScatterCFDEMCoeffs
{
    sigma   1.25e-5;
    C       0;
}

Restrictions

Combination with coarse graining is not tested.
