DESCRIPTION:Abstract:With the first detections of black hole-neutron star 
 (BHNS) mergers (GW200105 and GW200115) by the LIGO-Virgo-Kagra Collaborati
 on a significant scientific breakthrough was achieved. The physical interp
 retation of pre-and postmerger signals requires careful cross-examination 
 between observational and theoretical modelling results. In this talk\, I 
 will briefly introduce the BAM numerical relativity code and its capabilit
 ies in simulating compact object mergers. I will then present our work on 
 simulating excision initial data (ID) of BHNS binary constructed using the
  publicly available LORENE ID solver and evolved using moving puncture gau
 ge choices. Constrained solved and consistent ID are essential in accurate
 ly modeling compact object systems and a wider coverage of the parameter s
 pace is needed in exploring the dynamics of such systems. In this regard a
 nd with the availability of robust ID solvers like FUKA (public) and Ellip
 tica (inhouse) we are able to explore a wider parameter space with accurat
 e ID. Finally\, I will report some improvements in the simulations using I
 D from these solvers.
