Class
    Foam::ensightFaMesh
 
Description
    Encapsulation of area meshes for writing in ensight format.
 
Note
    Currently restricted to a single faMesh representation.
    The face elements are created from a specified subset of polyMesh
    faces. The original ordering of these faces is retained in the
    ensightFaces faceOrder().
