In this work we describe the construction of a computational tool to perform N-body simulations. It is a hybrid  integrator based on the MERCURY package Chambers (1999, MNRAS 304) that contains a symplectic second-order integrator (IS) and a Bulirsch-Stoer integrator (BS) for the treatment of close encounters between the bodies. We  developed a refinement in the collisions between the massive bodies, in order to determine the results of these collisions with more realism. We implemented the prescriptions proposed by Leinhardt & Stewart (2012, Apj 745), Genda et al. (2012, Apj 744), Marcus et al. (2010, Apj 719), and Mustill et al. (2018, MNRAS 478).
