Geometrical quantities and material properties are similar to those given by Curthoys and Oman (1987) and Rabbitt et al. (1999). The parameters N I, N II, and N r indicate the number of grid points in the axial direction for the active (I) and the passive (II) arms and in the radial direction, respectively
