Abstract

Multilevel substructuring algorithms in structural dynamics are considered together with their software implementation. The paper emphasizes a consistent data structure for representing objects on hierarchical levels. The data structure permits recursive numerical procedures to be easily implemented. As an example, a recursive multi-subspace iteration algorithm is introduced. The paper also considers the definition and implementation of a problem specification language. The language is similar to and retains the expressive power of Lisp. Finally, a numerical example is given.
