The paper describes GEPARD technique presenting connection between EGAK and DRACON techniques and TREK and DRACON techniques and designed for solution of complex two- and three-dimensional problems of polyphase medium dynamics including dynamics of solids under gas-dynamic (hydrodynamic) loading (the so-called connected aero- and hydroelasticity problems). Peculiarities of the mentioned techniques and principles of connection organization between them in consistent and multiple-processor modes are presented. Calculation results of the techniques taken separately as well as in connection mode are compared with experimental data.

Calculation results of EGAK and TREK techniques applying different methods of approximation of convective terms of equations (donor technique, RRM technique and concentration technique) are given. All calculations are conducted in Euler statement. The paper presents comparison and analysis of results obtained in calculations showing that concerning accuracy RRM technique has doubtless advantage over donor technique, and over concentration technique in some cases. Algorithm for combination of RRM and concentration techniques keeping their best features is suggested.
