Class
    Foam::fixedJumpFvPatchField

Description
    This boundary condition provides a jump condition, using the \c cyclic
    condition as a base.

    The jump is specified as a fixed value field, applied as an offset to the
    'owner' patch.

Usage
    \table
        Property     | Description             | Required    | Default value
        patchType    | underlying patch type should be \c cyclic| yes |
        jump         | current jump value      | yes         |
    \endtable

    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            fixedJump;
        patchType       cyclic;
        jump            uniform 10;
    }
    \endverbatim

    The above example shows the use of a fixed jump of '10'.

Note
     The underlying \c patchType should be set to \c cyclic
