SUNSHYNE Software for Modeling Compressible Gas Flows on Computer Systems with Hybrid CPU/GPU Architecture

The paper presents an overview of SUNSHYNE software system, designed for the numerical simulation of compressible gas flows on modern multiprocessor computational systems with high-performance graphical processing units. The software has a graphical user interface and allows computations in domains with complex geometries for industrial applications owing to a variety of implemented boundary conditions, support of unstructured and block structured grids, as well as integration with computer-aided design systems. Physical models, numerical methods, and functional capabilities of the system are described; examples of computations are presented, including computations of nonequilibrium flows, direct numerical simulation of the transition to turbulence, and modeling of heterogeneous detonation.
