The advent of high-speed computing machines is of particularly important value in numerical methods in all fields of the exact sciences, among them, gasdynamics, since it permits solutions of complete, unsimplified equations with an accuracy that completely satisfies and even exceeds practical requirements. The results have, in many cases, provided much more exact data than a simulated experiment, to say nothing of the fact that the calculation requires much lower expenditures than does an experiment. The characteristics feature of gasdynamics processes is that, generally speaking, they are accompanied by discontinuities in the functions defining the process (pressure, density, velocity, etc.). Therefore, for the numerical solution of problems in gasdynamics it was necessary to develop mathematical methods which permit discontinuous solutions.
