      An application program from the "Odnomerny Complex" package is described which is designed to calculate a 1-D time-dependent flow taking into account the impact of nonlinear heat conduction and external energy sources. Gas dynamics equation integration uses a through finite-difference method with artificial viscosity (a "crest"-type scheme). The energy equation is approximated by an implicit four-point difference scheme which is first order accurate in time. Four self-similar problems were used to compare numerical solutions obtained with self-similar ones.
