PARTITIONED ANALYSIS OF COUPLED DYNAMICAL SYSTEMS: RECENT ADVANCES

Abstract eng:
Methods for partitioned modeling and analysis, labeled as staggered solution procedure, were originally developed in the early 1970s to simulate coupled fluid-structure interaction problems by employing two single-discipline analysis modules. In the early 1980s a generalization of staggered procedure was developed, labeled as partitioned analysis, which can facilitate other types of interaction problems, including pore-fluid soil, structure-control, acoustic-structure, structural-thermal and structure-electromagnetic problems. All subsumed under the multi-physics simulations these days. The present lecture first will offer a brief review of the variationally derived partitioned analysis methods with examples of their successful applications. Then we focus on recent advances in the four categories: regularization for stiff coupled systems, reduced-order modeling, nonmatching interfaces, and consistent inverse mass matrices for explicit transient analysis. The presentation concludes with potential areas of further developments in partitioned analysis.
