Class
    Foam::partialSlipFvPatchField
 
Description
    This boundary condition provides a partial slip condition.  The amount of
    slip is controlled by a user-supplied field.
 
Usage
    \table
        Property      | Description             | Required    | Default value
        valueFraction | fraction of value used for boundary [0-1] | yes |
    \endtable
 
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            partialSlip;
        valueFraction   uniform 0.1;
        value           uniform 0;
    }
    \endverbatim
