Namespace
    Foam::meshWriters

Description
    A namespace for holding various types of mesh writers.


Class
    Foam::meshWriter

Description
    write OpenFOAM meshes and/or results to another CFD format
    - currently just STAR-CD

@par Files

    "constant/boundaryRegion" is an IOMap<dictionary> that contains
    the boundary type and names. eg,
    @verbatim
        (
            0
            {
                BoundaryType    wall;
                Label           Default_Boundary_Region;
            }

            1
            {
                BoundaryType    inlet;
                Label           inlet_1;
            }

            ...
