A mathematical model, a numerical algorithm, and an approach to its parallelization for the simulation of interior ballistics problems in the quasi-one-dimensional approximation using high performance computing are considered. The developed software is compared with a number of known application program packages for solving similar problems by the example of the AGARD test problem. The developed software can be used to solve a wide range of practically important problems in civil applications (such as the operation of gas generators, solid-propellant rocket engines or propellant charges for fire-fighting operations) and in special applications for the predictive modeling of interior ballistic processes in barrel systems.

Keywords: interior ballistics, numerical modeling, high performance computing
