The GAMM Committee for "Efficient Numerical Methods for Partial
Differential Equations" organizes seminars and workshops on subjects
concerning the algorithmic treatment of partial differential equations.
The topics are discretisation methods like the finite element and the
boundary element method for various type of applications in structural
and fluid mechanics. Particular attention is devoted to the advanced
solution methods. The series of such seminars was continued in 1995,
January 20-22, with the 11th Kiel-Seminar on the special topic Numerical
Treatment of Coupled Systems at the Christian-Albrechts-University of
Kiel. The seminar was attended by 100 scientist from 9 countries. 23
lectures were given, including two survey lectures. Different kinds of
couplings are considered in this volume. The coupling of different
components may occur in the physical model. On the other hand, a
coupling of subsystems can be generated by the numerical solution
technique. General examples of the latter kind are the domain
decomposition (see p. 128) or subspace decomposition (p. 117). The local
defect correction method couples different discretizations of the same
problem in order to improve the results, although the basic linear
system to be solved remains unchanged (p. 47). In general, the aim of
the numerical coupling is to make use of (efficient) subsystem solvers
(p. 1). The combination of different discretization techniques is
mentioned on page 59.
