      The paper considers unlimited adiabatic compression of gas regions with prism and cone shapes for which the exact, and approximate solutions are obtained by A.F. Sidorov. The discussion is given for the formulation in Lagrangian variables.
      Brief characteristics are given for Lagrangian D method using regular grid that was used for numerical simulation of gas compression.
      The numerical results are presented allowing to estimate the feasibility of numerical research for dense and fast jets with D code by comparing with analytical and approximate solutions. The numerical solutions are obtained by setting the velocity and pressure on a moving flexible piston.
