  Using numerical methods we discuss the effects of open boundary conditions on
condensation phenomena in the zero-range process (ZRP) and transport processes
with pair-factorized steady states (PFSS), an extended model of the ZRP with
nearest-neighbor interaction. For the zero-range process we compare to
analytical results in the literature with respect to criticality and
condensation. For the extended model we find a similar phase structure, but
observe supercritical phases with droplet formation for strong boundary drives.
