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:

Property	Description	Type	Required	Default
type	Type name: JohnsonJacksonParticleSlip	word	yes	-
specularityCoefficient	Specularity coefficient [-]	dimensionedScalar	yes	-

The inherited entries are elaborated in:

• partialSlipFvPatchFields.H

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