Class
    Foam::uniformJumpFvPatchField

Description
    This boundary condition provides a jump condition, using the \c cyclic
    condition as a base.  The jump is specified as a time-varying uniform
    value across the patch.

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

    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            uniformJump;
        patchType       cyclic;
        jumpTable       constant 10;
    }
    \endverbatim

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

Note
    The uniformValue entry is a Function1 type, able to describe time
    varying functions.  The example above gives the usage for supplying a
    constant value.

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