Simulation of astrophysical phenomena on the basis of high-performance computations

Аннотация

A solution algorithm developed for three-dimensional magnetogasdynamic problems is used to simulate the accretion of interstellar matter onto a massive astronomical object with the formation of collinear jets. A kinetically consistent algorithm is well adapted to the architecture of high-performance computer systems with massive parallelism and has improved conditions for time discretization. The three-dimensional accretion of interstellar matter is computed in detail on a spatial grid consisting of 1 billion nodes, and the possibility of studying the formation of collinear jets is demonstrated.
