  The multiconfiguration Dirac-Hartree-Fock (MCDHF) method has been employed to
calculate atomic electric dipole moments (EDM) of 225^Ra, 199^Hg, and 171^Yb.
For the calculations of the matrix elements we extended the relativistic atomic
structure package GRASP2K. The extension includes programs to evaluate matrix
elements of (P, T)-odd e-N tensor-pseudotensor and pseudoscalar-scalar
interactions, the atomic electric dipole interaction, the nuclear Schiff
moment, and the interaction of the electron electric dipole moment with nuclear
magnetic moments. The interelectronic interactions were accounted for through
valence and core-valence electron correlation effects. The electron shell
relaxation was included with separately optimised wave functions of opposite
parities.
