partialSlip

Description

The partialSlip is a velocity boundary condition that determines the amount of slip is controlled by a user-supplied field.

Usage

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

Boundary file

<patchName>
{
    type            wall;
    ...
}

Field file

<patchName>
{
    // Mandatory entries
    type            partialSlip;
    valueFraction   <Field>;

    // Optional entries
    refValue        <Field>;
    writeValue      <bool>;

    // Inherited entries
    ...
}

where:

Property	Description	Type	Required	Default
type	Type name: partialSlip	word	yes	-
valueFraction	Fraction of refValue used for boundary [0-1]	Field	yes	-
refValue	Reference value at zero slip	Field	no	Zero
writeValue	Flag to output patch values (e.g. for ParaView)	bool	no	false
