The paper briefly describes SATURN code for the numerical simulation of 2D and 3D time-dependent and time-independent neutron transport and nonlinear energy transport by gammas, ions, electrons and fast-moving charged particles. The transport equation is solved in kinetic and diffusion approximations.
Code SATURN is oriented to simulations on modern distributed-memory multiprocessor supercomputers.
The main ideas on which the code is based are described. Physico-mathematical models and mathematical methods used to solve the above-mentioned classes of multidimensional problems are formulated, as well as paralleling algorithms are described.Keywords: two-dimensional and three-dimensional problems of neutron and X-ray transport, kinetic and diffusion multiple-group approximation, SATURN code, difference schemes, paralleling algorithms.
