    The hot spot is approximated by the region of high pressure accumulation due to multiple shock reverberations within the polymer binder, surrounded by the bulk of explosive. The meso-scale Smoothed Particle Hydrodynamic (SPH) simulation is adopted to first identify the peak temperatures within the hot spots. These peak temperatures obtained from mesoscale level are then used to initialize the random sites of heat release prior to carrying out the full scale hydrodynamic simulation of shock-to-detonation transition (SDT). For validation of the simulation, a rate stick of 18-mm in radius is experimentally tested. The comparison showed that detonation properties of the explosive are well characterized, and further no-go was witnessed if no mesoscale hot spot model is considered into the hydrodynamic simulation. Thus, the SDT process can be well described by the present model based on the multi-scale hot spot initiation.
