ABSTRACT
The Kaa matrix is free of constraints and ready for analysis. However, for computational advantages it may be further reduced. Let us partition the remaining degrees of freedom into two groups. One such physical partitioning may be based on considering the boundary degrees of freedom as one, and the interior degrees of freedom as the other partition. This is a single-level, single-component static condensation, the topic of Section 8.1. One of the first publications related to this topic is [2].
