Class
    Foam::surfaceWriters::abaqusWriter

Description
    A surface writer for the ABAQUS file format - both surface mesh and fields

    The formatOptions for abaqus:
    \table
        Property    | Description                           | Reqd | Default
        scale       | Output geometry scaling               | no  | 1
        transform   | Output coordinate transform           | no  |
        fieldLevel  | Subtract field level before scaling   | no  | empty dict
        fieldScale  | Output field scaling                  | no  | empty dict
        noGeometry  | Suppress geometry output (beta feature) | no  | false
    \endtable

    For example,
    \verbatim
    formatOptions
    {
        abaqus
        {
            scale   1000;     // [m] -> [mm]
            fieldLevel
            {
                p       1e5;    // Absolute -> gauge [Pa]
            }
            fieldScale
            {
                "p.*"   0.01;   // [Pa] -> [mbar]
            }
        }
    }
    \endverbatim

    \section Output file locations

    The \c rootdir normally corresponds to something like
    \c postProcessing/<name>

    \subsection Geometry
    \verbatim
    rootdir
    `-- surfaceName0
        `-- geometry
            `-- surfaceName0_<time>.abq
    \endverbatim

    \subsection Fields
    \verbatim
    rootdir
    `-- surfaceName0
        `-- field0
        |   `-- surfaceName0_<time>.{inp}
        `-- field1
            `-- surfaceName0_<time>.{inp}
    \endverbatim

Note
    Output variable scaling does not apply to integer types such as Ids.
