An evaluation of quasi-Newton methods for application to FSI problems involving free surface flow and solid body contact

Author: Bogaers, Alfred EJ ; Kok, S ; Reddy, BD ; Franze, T Date: Sep 2016 The design of coupling algorithms for partitioned fluid–structure interaction (FSI) simulations are typically validated on FSI problems involving large deformations of thin elastic structures with large added mass ratios. A large number of ... Read more
Extending the robustness and efficiency of artificial compressibility for partitioned fluid-structure interactions

Author: Bogaers, Alfred EJ ; Kok, S ; Reddy, BD ; Franz, T Date: Jan 2015 In this paper we introduce the idea of combining artificial compressibility (AC) with quasi-Newton (QN) methods to solve strongly coupled, fully/quasi-enclosed fluid-structure interaction (FSI) problems. Partitioned, incompressible, FSI based ... Read more
Quasi-Newton methods for implicit black-box FSI coupling

Author: Bogaers, Alfred EJ ; Kok, S ; Reddy, BD ; Franz, T Date: Sep 2014 In this paper we introduce a new multi-vector update quasi-Newton (MVQN) method for implicit coupling of partitioned, transient FSI solvers. The new quasi-Newton method facilitates the use of 'black-box' field solvers and under certain ... Read more
