Class
    Foam::fixedProfileFvPatchField

Description
    This boundary condition provides a fixed value profile condition.

Usage
    \table
        Property     | Description       | Required | Default value
        profile      | Profile function  | yes      |
        direction    | Direction of the line along which the profile is \\
                               evaluated | yes      |
        origin       | Origin of the line along which the profile is \\
                               evaluated | yes      |
    \endtable

    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            fixedProfile;
        profile
        {
            type                table;
            file                "UProfile";
            format              csv;
            nHeaderLine         0;
            columns             (0 (1 2 3));
            separator           ",";
            mergeSeparators     no;
            outOfBounds         clamp;
            interpolationScheme linear;
        }
        direction        (0 1 0);
        origin           0;
    }
    \endverbatim

    Example setting a parabolic inlet profile for the pitzDaily case:
    \verbatim
    inlet
    {
        type            fixedProfile;
        profile         polynomial
        (
            ((1 0 0)        (0 0 0))
            ((-6200 0 0)    (2 0 0))
        );
        direction       (0 1 0);
        origin          0.0127;
    }
    \endverbatim
