An experimental investigation and a numerical simulation of detonation excitation of TATB explosives were undertaken. The experimental investigation was carried out for a detonation excitation at an interaction of shocks with different intensity as well as for the effects of desensitizing (explosive sensitivity decrease) and sensitizing (explosive sensitivity increase). A numerical simulation of experiments was performed on LEGAK complex using kinetics of explosion decomposition, proposed by Morozov group and implemented in Lagrangian setting in DMK, MIMOZA and D-methods. Kinetics model was generalized to non Lagrangian calculational grid. Calculational results and their comparison with experimental data are presented. The experimental and calculational data agree with each other. The whole set of experiments has been described with fixed kinetic and calculation parameters.

The paper describes SOVT service application used to accumulate, process and present results obtained in the numerical simulation of mathematical physics problems. SOVT incorporates a number of independent modules interacting through a database of standard time tables (STTBD) managed by Oracle. The modules interact with STTBD independently (converters), or as components of code packages (libraries of STTBD access procedures), or as components of specialized data processing and presentation systems (STTBD access server). SOVT selects from STTBD information on several functions of different problems calculated by different codes, provides their preliminary processing, and forwards them for further processing and analysis made with the standard data processing and presentation systems (Matlab, Excel) or with a specialized data visualization system VIZI1D, developed in RFNC-VNIITF.

A service application for analyzing the results of problems simulated by different software complexes and stored in the database of standard time tables is described. With this application results a great number of problems is analyzed with the same promptness regardless of when they were obtained and whether they were obtained by one or more codes. The application Is based on the STTBD access server and VIZI-ID, Matlab and MS Excel data processing and visualization systems. It is written in C++ for Microsoft Visual Studio with use of COM technology and Oracle database management system.
