The multimessenger detection of the kilonova GW170817 from the merger of two neutron stars has revealed clues to the formation of heavy elements than iron. Meanwhile, several interesting questions related to the properties of the radioactively powered ejecta remain. In this project, we parametrize the outflow properties around the merger remnants and investigate the role of feedback from nuclear heating on the outflow of kilonova ejecta relevant to heavy-element nucleosynthesis via long-term axisymmetric hydrodynamic simulations.
