Class
    Foam::fixedProfileFvPatchField

Group
    grpGenericBoundaryConditions

Description
    This boundary condition provides a fixed value profile condition.

Usage
    \table
        Property     | Description              | Required | Default value
        profile      | Profile Function1        | yes |
        direction    | Profile direction        | yes |
        origin       | Profile origin           | yes |
    \endtable

    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type       fixedProfile;
        profile    csvFile;

        profileCoeffs
        {
            nHeaderLine         0;          // Number of header lines
            refColumn           0;          // Reference column index
            componentColumns    (1 2 3);    // Component column indices
            separator           ",";        // Optional (defaults to ",")
            mergeSeparators     no;         // Merge multiple separators
            file                "Uprofile.csv";  // name of csv data file
            outOfBounds         clamp;      // Optional out-of-bounds handling
            interpolationScheme linear;     // Optional interpolation scheme
        }
        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

Note
    The profile entry is a Function1 type.  The example above gives the
    usage for supplying csv file.
