Sommario/riassunto |
|
A need for a deeper understanding of the convergence properties of augmented Lagrangian algorithms and of their relationship to operator-splitting methods such as alternating-methods direction and the development of more efficient algorithms prompted the authors to write this book. The volume is oriented to applications in continuum mechanics. This volume deals with the numerical simulation of the behavior of continuous media by augmented Lagrangian and operator-splitting methods (coupled to finite-element approximations). It begins with a description of the mechanical and mathematical frameworks of the considered applications as well as a general analysis of the basic numerical methods additionally used to study them. These ideas are then applied to specific classes of mechanical problems. |

Sommario/riassunto |
|
Expanding upon the ideas proposed in his seminal book, the author offers the treatment of the magnetohydrodynamic theory of spontaneous magnetic discontinuities. He shows how it can be used to |
|
|
|
|
|
|
|
|
|
|
explain the activity of the external magnetic fields of planets, interstellar gas clouds, galaxies, and the magnetic fields in laboratory plasmas. |
