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
