Improving Condensation Methods in the Presence of General Masters by a Modified Rayleigh Functional
In the dynamic analysis of structures condensation methods are often used to reduce the number of degrees of freedom to manageable size. The approximation properties of these methods can be enhanced considerably taking advantage of the exactly condensed problem and the corresponding Rayleigh functional or by using general masters. In this note we discuss how to combine these two approaches.
