A comparison of different quasi-newton acceleration methods for partitioned multi-physics codes

Author: Haelterman, R ; Bogaers, Alfred EJ ; Degroote, J Date: Feb 2018 In many cases, different physical systems interact, which translates to coupled mathematical models. We only focus on methods to solve (strongly) coupled problems with a partitioned approach, i.e. where each of the physical problems is solved ... Read more
Development of a partitioned finite volume-finite element fluid-structure interaction scheme for strongly-coupled problems

Author: Suliman, Ridhwaan ; Oxtoby, Oliver F ; Malan, AG ; Kok, S Date: Jul 2012 This work details the development of a computational tool that can accurately model strongly-coupled fluid-structure interaction (FSI) problems, with a particular focus on thin-walled structures undergoing large, non-linear deformations. The ... Read more
Development of strongly coupled FSI technology involving thin walled structures

Author: Suliman, Ridhwaan ; Oxtoby, Oliver F ; Malan, AG ; Kok, S Date: Jan 2011 A strongly coupled finite volume-finite element fluid-structure interaction (FSI) scheme is developed. Both an edge-based finite volume and Galerkin finite element scheme are implemented and evaluated for modelling the mechanics of solids. ... Read more
Experimental and numerical validation of a simplified rigid torso surrogate used for investigating the fluid-structure interaction of air blast waves

Author: Pandelani, Thanyani A ; Schutte, Zelldra ; Wium, Elsmari Date: Sep 2018 Blast waves from landmines and Improvised Explosive Devices (IEDs) produce an almost instantaneous rise in pressure which causes Primary Blast Injuries (PBI). The primary blast injuries are caused directly by the blast wave and encompasses ... Read more

A matrix free, partitioned solution of fluid-structure interaction problems using finite volume and finite element methods

Author: Suliman, Ridhwaan ; Oxtoby, Oliver F ; Malan, AG ; Kok, S Date: Jan 2015 A fully-coupled partitioned finite volume–finite volume and hybrid finite volume–finite element fluid-structure interaction scheme is presented. The fluid domain is modelled as a viscous incompressible isothermal region governed by the ... Read more
The stability and dynamic behaviour of fluid-loaded structures

Author: Suliman, Ridhwaan ; Peake, N Date: Jul 2015 The deformation of slender elastic structures due to the bulk motion of fluid around it is a common multiphysics problem encountered in many applications. In this work we implement two computational FSI approaches in a partitioned manner: a ... Read more
