Class
    Foam::fanFvPatchField

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

    The jump is specified as a \c Function1 type, to enable the use of, e.g.
    contant, polynomial, table values.

Usage
    \table
        Property     | Description             | Required    | Default value
        patchType    | underlying patch type should be \c cyclic| yes |
        jumpTable    | jump data, e.g. \c csvFile | yes      |
        phi          | flux field name         | no          | phi
        rho          | density field name      | no          | none
    \endtable

    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            fan;
        patchType       cyclic;
        jumpTable       csvFile;
        csvFileCoeffs
        {
            hasHeaderLine   1;
            refColumn       0;
            componentColumns 1(1);
            separator       ",";
            file           "$FOAM_CASE/constant/pressureVsU";
        }
        value           uniform 0;
    }
    \endverbatim

    The above example shows the use of a comma separated (CSV) file to specify
    the jump condition.

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