The formulation of 1D boundaryvalue problems in radiation gas dynamics approximated with radiant heat conduction equations for heterogeneous media is considered. A calculation method based on the gas dynamics approximation with the "Crest" scheme is briefly described. The heat transfer is computed using a purely implicit difference scheme. The package structure and its principal capabilities are given.

An application package is described for solving boundaryvalue problems associated with a system of differential equations having a single space and time variable assuming its quasi1 inearity and the correctness of the problem formulation. The package is shown to be suitable for solving a broad class of problems in the continuum mechanics, neutron physics, radiation physics, magnetic field etc. The package structure description introduces a "production run” notion, points out a substantial difference between an operational program and methodical one, shows a way for minimizing application program machinedependencies when moving the complex on other computers. The operation practice analysis revealed the complex efficiency increasing reserve and some ways for its improvement are outlined.
