Identification of Multiscale Vortex Structures and Transition Fluid Features in CFD and Numerical Astrophysics

Abstract

The need for effective postprocessor analysis of the results of extensive calculations on supercomputers remains extremely high when using new complex computing systems in modeling super- and hypersonic gas flows, predictive modeling of heat and mass transfer processes in jet engines and new energy devices, in solving multiscale problems for astrophysical simulation. Requirements for improving the quality and versatility of new software and visualization codes are increasing with the transition to exascale computing, which requires the improvement of new service systems, in particular systems for visualizing and analyzing the results of multi-scale calculations with dramatically increased input and output data. This paper considers the experience of using an authorized visualization system in the practice of solving some tasks with vortex flow structures and unpredictable instability.
