Interior and modal masters in condensation
methods for eigenvalue problems
Author(s): Heinrich Voss
Abstract:
In the dynamic analysis of structures condensation methods are often used
to reduce the number of degrees of freedom to manageable size.
Substruc-
turing and choosing the master variables as the degrees of freedom on the
interfaces of the substructures yields data structures which are well suited
to be implemented on parallel computers.
In this paper we discuss the addi-
tional use of interior masters and modal masters in substructuring.
The data
structure is preserved such that the condensed problem can be determined
substructurewise.
1 Introduction
In the analysis of the dynamic response of a linear structure using finite ele-
ment methods very often prohibitively many degrees of freedom are needed
to model the behaviour of the system sufficiently accurate...
