Abstract:	Development of object oriented 3D dynamic simulation of the particle is considered. This code is based on the soft sphere model dealing with both normal force , tangential force and the friction. The development of such a model and the code is motivated by the need to understand the flow patterns of granular material. The prime effort while developing this code was focused on the data encapsulation and secured access to all the attributes of all physical parameters of the bulk solid, which might be endangered by the random access of the interface of the software. A dynamically bound array based container has been implemented though needs some more work to be done to make it more robust. Data sorting and searching is also focused. Reduction of computation overhead and increase of speed were tried to resolve through established algorithms on searching and sorting. This is of crucial importance in dealing with problems associated with bulk solids flows, which occur in almost all industries and natural geological events.
