Detonation initiation by shock is an important issue in the explosive safety assessment and design of the explosive train and explosive devices. Experimental studies in this area are very difficult, expensive, and require advanced equipment. Therefore, simulation is a useful and suitable way for studying this phenomenon. The purpose of this article is to develop a one-dimensional computer code for simulation of the direct initiation of energetic materials. The Fortran SIN hydrocode, was used for this purpose and the I&G burn model was added to this code. The developed code was used to simulate the direct initiation of the Comp-B by sustained shock pulses. A good agreement was observed between the present simulation results and the results of other references. For example, in the simulation of the initiation of Comp-B by 3.78 GPa shock, the run distance to detonation was 14.8mm, which the difference between this value and the reported experimental data is 5.7%.
