Desire to model in ever increasing detail geometrical and physical features has lead to a steady increase in the number of points used in field solvers. Sequential generation of meshes of large size is extremely problematic both in terms of time and memory requirements. The book gives the extensive introduction to the subject of numerical grid generation with the emphases on unstructured meshes. Various approaches to domain decomposition and partitioning criteria are described. Then detailed explanation of the parallel mesh generation algorithm proposed in this book is given. Special attention is paid to implementation issues and coupling of developed parallel grid generator with FEM solvers. Several real-life examples are shown and questions regarding time and memory consumption, efficiency of computations and quality of generated meshes are discussed. This book is of theoretical and practical use to the people who are interested in modern and leading-edge developments in mesh generation, domain decomposition methods, distributed computing as well as to mathematicians and engineers from adjoining areas who do not have any background in this field, but want to have a good start.
