Class
    Foam::fixedNormalSlipFvPatchField
 
Description
    This boundary condition sets the patch-normal component to a fixed value.
 
Usage
    \table
        Property     | Description             | Required    | Default value
        fixedValue   | fixed value             | yes         |
    \endtable
 
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            fixedNormalSlip;
        fixedValue      uniform 0;     // example entry for a scalar field
    }
    \endverbatim
