Interface information transfer between non-matching, nonconforming interfaces using radial basis function interpolation

Author: Bogaers, Alfred EJ ; Kok, S ; Reddy, BD ; Franz, T Date: Oct 2016 In this paper we outline the use of radial basis function interpolation (RBF) to transfer information across non-matching and nonconforming interface meshes, with particular focus to partitioned fluid-structure interactions (FSI). In general, ... 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
Strongly coupled partitioned FSI using proper orthogonal decomposition

Author: Bogaers, Alfred EJ ; Kok, S ; Franz, T Date: Dec 2012 In this paper we present a strong coupling algorithm for partitioned fluid-structure interactions which can be applied to black-box field solvers. The coupling algorithm constructs an approximate interface Jacobian of the coupled fluid-structure ... Read more
Towards the development of a fully coupled arterial-venous 1D model: suitability of using a 1D finite volume method with staggered spatial discretization

Author: Bogaers, Alfred EJ ; De Villiers, AM ; Kok, S ; Ubbink, O ; Franz, T ; Reddy, BD ; Du Toit, CG Date: Jul 2012 In this paper we outline the development of a 1D finite volume model to solve for blood flow through the arterial system. The model is based on a staggered spatial discretization which leads to a stable solution scheme. This scheme can ... Read more
Treatment of fully enclosed FSI using artificial compressibility

Author: Bogaers, Alfred EJ ; Kok, S ; Reddy, BD ; Franz, T Date: Jul 2013 In recent years a great deal of advances have been made with respect to Dirichlet-Neuman (DN) partitioned fluid-structure interaction (FSI) solvers. Problems of varying degrees of complexity can be solved with reasonable efficiencies through ... Read more
