We discuss mass transfer in eccentric binaries containing a white dwarf and a
neutron star (WD--NS binaries). We show that such binaries are produced from
field binaries following a series of mass transfer episodes that allow the
white dwarf to form before the neutron star. We predict the orbital properties
of binaries similar to the observed WD--NS binary J1141+6545, and show that
they will undergo episodic mass transfer from the white dwarf to the neutron
star. Furthermore, we describe oil-on-water, a two-phase SPH formalism that we
have developed in order to model mass transfer in such binaries.
