58 * Initialize FVM to EnSight Gold file writer.
59 *
60 * Options are:
61 * text output text files
62 * binary output binary files (default)
63 * big_endian force binary files to big-endian
64 * discard_polygons do not output polygons or related values
65 * discard_polyhedra do not output polyhedra or related values
66 * divide_polygons tesselate polygons with triangles
67 * divide_polyhedra tesselate polyhedra with tetrahedra and pyramids
68 * (adding a vertex near each polyhedron's center)
69 *
70 * parameters:
71 * name <-- base output case name.
72 * options <-- whitespace separated, lowercase options list
73 * time_dependecy <-- indicates if and how meshes will change with time
74 * comm <-- associated MPI communicator.
75 *
76 * returns:
77 * pointer to opaque EnSight Gold writer structure.
