This book discusses the introduction of isogeometric technology to the boundary element method (BEM) in order to establish an improved link between simulation and computer aided design (CAD) that does not require mesh generation. In the isogeometric BEM, non-uniform rational B-splines replace the Lagrange polynomials used in conventional BEM. This may seem a trivial exercise, but if implemented rigorously, it has profound implications for the ...

The book presents the state of the art in isogeometric modeling and shows how the method has advantaged. First an introduction to geometric modeling with NURBS and T-splines is given followed by the implementation into computer software. The implementation in both the FEM and BEM is discussed.

Suitable for professionals and advanced students in underground engineering, this book presents techniques that focus on reducing time, cost and risk in the construction and maintenance of underground facilities.

This text presents the results of the joint research initiative "Numercial Simulation in Tunneling". In doing so it provides a thorough guide to improving the safety and economy of tunnels by discussing the application of numerical simulation methods to assist tunnel engineers. Numerical simulation tools for the estimation of the required tunnel support and the required construction measures are described in this book. By using them, it is pos...

This thorough yet understandable introduction to the boundary element method presents an attractive alternative to the finite element method. It not only explains the theory but also presents the implementation of the theory into computer code, the code in FORTRAN 95 can be freely downloaded. The book also addresses the issue of efficiently using parallel processing hardware in order to considerably speed up the computations for large systems....

Randwertmethoden wendet man zur Lösung vielfältiger physikalischer Probleme an. Da man auf diese Weise eine vollständige Lösung ausschließlich in Abhängigkeit von Randwerten erhalten kann, werden diese zeitsparenden und zuverlässigen Verfahren auch in der Technik immer beliebter. Dieser Band erklärt Randwertmethoden weniger mathematisch als aus der Sicht des Anwenders. Programmiert wird mit FORTRAN 95. (07/00)
