I. D. Sofronov Vant. Ser. Metodiki i Programmy Chislennogo Resheniya Zadach Matematicheskoy Fiziki. 1978. No 1. P. 36.
The paper is the first of the serial papers describing the software package for solving 1D mathematical physics problems. A production program is defined and its difference from a methodical one is considered. Demands for production programs are formulated. The package structure is described. The concept of package complexity is explicated. The content of the 1976 complex version is considered.
 ON SOLUTION PROPERTIES OF AN INTEGRAL EQUATION OF RADIATION TRANSFER Yu. N. Babayev, S. V. Bazhenov, Yu. A. Dementyev Vant. Ser. Metodiki i Programmy Chislennogo Resheniya Zadach Matematicheskoy Fiziki. 1978. No 1. P. 79.
The paper deals with quality analysis of solution of the nonstationary integral equation of radiation transfer from a surface, radiating according to the Lambert law, through a region of negligible radiationmatter interaction.
 A NUMERICAL S0LUTI.9N METHOD FOR SPHERICALLYSYMMETRIC SPECTRAL PROBLEMS OF HEAT RADIATION TRANSFER O. A. Dibirov, V. A. Elesin, V. E. Troshchiev, V. F. Yudintsev Vant. Ser. Metodiki i Programmy Chislennogo Resheniya Zadach Matematicheskoy Fiziki. 1978. No 1. P. 1017.
The sphericallysymmetric spectral (group) problem of heat radiation transfer and numerical solution method for the problem are formulated. The method is based on combination of the first and secondorder finitedifference approximations and on iterative amendment algorithm used to solve a set of nonlinear difference equations. Convergence of iterations and accuracy of mesh solutions are discussed. A numerical solution of a multigroup problem is given.
 SCALE EFFECT ANALYSIS UNDER DYNAMIC LOADS BASED ON DESTRUCTION TIME CRITERION S. M. Bakhrakh, N. P. Kovalyov, Yu. V. Yanilkin Vant. Ser. Metodiki i Programmy Chislennogo Resheniya Zadach Matematicheskoy Fiziki. 1978. No 1. P. 1820.
Shell benavior resulting from a systemcentered HE burst is investigated numerically. The scale effect occurring in associated experiments may be understood using a destruction time criterion.
 UPCODE FOR 1D GAS DYNAMICS AND ELASTOPLASTIC PROBLEMS OF CONTINUUM MECHANICS V. A. Batalov, V. A. Svidinski, V. I. Selin, V. N. Sofronov Vant. Ser. Metodiki i Programmy Chislennogo Resheniya Zadach Matematicheskoy Fiziki. 1978. No 1. P. 2128.
A code to solve 1D continuum mechanics problems is described, allowing to account the following physical processes: gas dynamics, elastoplastic deformation on the basis of Prandt1Reiss plastic flow laws, explosive detonation, breakoff and radial fracturing, diffusionapproximated heat conductivity. Finite difference walkthrough pseudoviscosity method ("CREST"scheme) is used for numerical solution of the gas dynamics system. Radial fracturing, evaporation, melting and explosive detonation are realized in the program through the equation of state. The program is blockstructured and has dynamic memory allocation. The program computer complex linking is made depending on the type of symmetry of the problem being computed. Problem capabilities are demonstrated by computing 6 test problems.
