This paper have analyzes the influence of parallelization and computational grid parameters on execution time analysis of gas-dynamic flow and stress-strain state of the structure in the experimental equipment. It discusses some results of computational experiments. Physical, mathematical, and solid-state grid models were developed separately for gas dynamic tasks and tasks the theory of elasticity. The some results discuss of computational experiments. It is found that the strength's calculation's scalability lower than gas flow's process in the evaluation. Preliminary analysis has shown that the velocity of gas-dynamic processes of calculation raises at parallelization process optimization and constructing the mesh. Scalability is not increased the evaluation of stress-strain state of the structure. Possible that duration of the calculation will be unacceptable at the decision of related the tasks in relation to dynamical systems “gas-construction” in the system engineering analysis Ansys. For solving this kind of tasks may need to develop new algorithms.
Keywords: gas dynamic flow, stress-strain state of the structure, the experimental equipment, computational experiment, vibration, scalability, parameters of the computational grid, paralleling.
