Abstract: FIELD: information technology.  
     SUBSTANCE: invention relates to the field of information technologies intended for specialized data processing, in particular to a method for computational modeling of combustion gas dynamics processes occurring in a certain material medium that permits chemical transformations. The method for computational modeling of combustion gas dynamics processes occurring in a material medium that permits chemical transformations includes the following actions carried out sequentially: determination of the initial data describing interrelated physico-chemical and dynamic processes in the initial specified material medium that permits chemical transformations, decomposition of the specified material medium into geometric regions, each of which corresponds to its own set of initial data of the specified physico-chemical and dynamic processes, decomposition of these physico-chemical and dynamic processes into gas-dynamic, thermodiffusion and chemical processes is carried out for each specified geometric region, the subsequent processing of the specified data changing in time in each geometric region is carried out using a hybrid cluster system of parallel computing, each node of which includes a set of computing devices, such as: at least one general-purpose processor and at least one coprocessor. After determining the initial data, the specified initial data describing the course of the specified processes in time is recorded and an initial digital copy of the specified material medium is created, and the subsequent processing of the specified data changing in time in each geometric region using the node of the specified cluster system is carried out, respectively, for gas-dynamic and thermodiffusion processes on at least one general-purpose processor, and for chemical processes on at least one coprocessor, which is used as a specialized coprocessor focused on solving rigid systems of equations used, among other things, when solving combustion problems, while processing is carried out taking into account data from the boundaries of neighboring geometric regions and the time of the processes themselves to a given finite time, after that, changes in the parameters of these gas-dynamic and thermodiffusion processes are determined over time in each geometric region, taking into account the flow of chemical processes, and a new digital copy corresponding to a given finite time is constructed, and based on this digital copy, data describing interrelated physico-chemical and dynamic processes occurring in the specified material medium is determined.  
     EFFECT: increased accuracy of calculations and reduced time of their implementation when constructing a real digital model, which will reduce the time for developing a digital twin that permits predicting the flow of combustion gas dynamics processes in a material environment that permits chemical transformations.
