Class
    Foam::surfaceNormalUniformFixedValueFvPatchVectorField
 
Description
    Surface-normal fixed value vector boundary condition
 
    in which the vector field is obtained by scaling the patch normals
    by the evaluated scalar Function1 provided.
 
Usage
    \table
        Property     | Description             | Required    | Default value
        uniformValue | uniform value           | yes         |
    \endtable
 
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            surfaceNormalUniformFixedValue;
        uniformValue    constant -0.2;         // 0.2 INTO the domain
    }
    \endverbatim
 
    Note:
        Sign conventions:
      - the value is positive for outward-pointing vectors
