Recent experimental observations of the charged hadron properties in collisions at 193 GeV contradict many of the theoretical models of particle production including two-component Monte Carlo Glauber model. The experimental results show a small correlation between the charged hadron properties and the initial geometrical configurations (e.g. body–body, tip–tip etc.) of collisions. In this article, we have modified the Monte Carlo HYDJET++ model to study the charged hadron production in collisions at 193 GeV center-of-mass energy in tip–tip and body–body initial configurations. We have modified the hard as well as soft production processes to make this model suitable for collisions. We have calculated the pseudorapidity distribution, transverse momentum distribution and elliptic flow distribution of charged hadrons with different control parameters in various geometrical configurations possible for collision. We find that HYDJET++ model supports a small correlation between the various properties of charged hadrons and the initial geometrical configurations of collision. Further, the results obtained in modified HYDJET++ model regarding 
and elliptic flow (
) suitably matches with the experimental data of collisions in minimum bias configuration.
