We present a new technique to perform refinements on acute type tetrahedral partitions of a polyhedral domain, provided that the center of the circumscribed sphere around each tetrahedron belongs to the tetrahedron. Theresulting family of partitions is of acute type; thus, all the tetrahedra safisfy the maximum angle condition. Both these properties are highly desirable in finite element analysis.
