Pairing MBE(n) with DFT results in slow convergence of the n-body interactions for neutral systems and rapid divergence for hydrated ions, using a variety of common GGA and meta-GGA functionals. Hybrid functionals with 20-25% Fock exchange continue to show unphysical oscillations in the n-body interactions, and functionals such as BH&H-LYP (with 50% Fock exchange) are required in order to eliminate SIE-induced divergence. The latter functional may be a useful workaround. A DC-DFT correction scheme 132-134 has shown preliminary promise in small-cluster MBE(n) calculations, but it does not solve the aforementioned problem in a general way.
