| Popis: | Smoothed Particle Hydrodynamics is a multidimensional Lagrangian method of numerical hydrodynamics that has been used to tackle a wide variety of problems in astrophysics. Here we develop the basic equations of the SPH scheme, and we discuss some of its numerical properties and limitations. As an illustration of typical astrophysical applications, we discuss recent calculations of stellar interactions, including collisions between main sequence stars and the coalescence of compact binaries. 21 pages, invited review paper to appear in Journal of Computational and Applied Mathematics (JCAM). Fig. 2 is available from the authors in hardcopy form only. Revised, slightly abbreviated version |
