Usage🔗

The condition requires entries in both the boundary and field files.

Boundary file🔗

<patchName>
{
    type            patch;
    ...
}

Field file🔗

<patchName>
{
    // Mandatory entries
    type            JohnsonJacksonParticleSlip;
    specularityCoefficient  <dimensionedScalar>;

    // Inherited entries
    ...
}

where:

The inherited entries are elaborated in:

• partialSlipFvPatchFields.H

• The specularity coefficient has to be within (0, 1).
