  This paper deals with a simple and straightforward procedure for automatic
generation of finite-element or finite-volume meshes of spheroidal domains,
consisting of tetrahedra. Besides the equation of the boundary, the generated
meshes depend only on an integer parameter, whose value is associated with the
degree of refinement. More specifically the procedure applies to the case where
the boundary of a curved three-dimensional domain not so irregular can be
expressed in spherical coordinates, with origin placed at a suitable location
in its interior. An optimal numbering of mesh elements and nodes can be
accomplished very easily. Several examples indicate that the generated meshes
form a quasi-uniform family of partitions, as the corresponding value of the
integer parameter increases, as long as the domain is not too distorted.
