Wendland, H. (author)This paper gives a survey on kernel-based scattered data interpolation methods in the context of static aeroelastic computations. We describe the general procedure, address problems and solutions for large-scale data sets, for flat data sets, and for rotational information. Finally, we demonstrate the versatility of the method by showing two...conference paper 2006

Witteveen, J.A.S. (author), Bijl, H. (author)A robust and efficient uncertainty quantification method is presented for resolving the effect of uncertainty on the behavior of multi-physics systems. The extrema diminishing method in probability space maintains a bounded error due to the interpolation of deterministic samples at constant phase in a transonic airfoil flutter problem.conference paper 2009

Michler, C. (author), Van Brummelen, E.H. (author), In 't Groen, R. (author), De Borst, R. (author)The numerical solution of fluid-structure interactions with the customary subiteration method incurs numerous deficiencies. We validate a recently proposed solution method based on the conjugation of subiteration with a Newton-Krylov method, and demonstrate its superiority and beneficial characteristics.conference paper 2006

Fernandes, O. (author), Blom, D.S. (author), Frey, S. (author), Van Zuijlen, A.H. (author), Bijl, H. (author), Ertl, T. (author)We present an integrated in-situ visualization approach for partitioned multi-physics simulation of fluid-structure interaction. The simulation itself is treated as a black box and only the information at the fluid-structure interface is considered, and communicated between the fluid and solid solvers with a separate coupling tool. The...conference paper 2015

Dunne, T. (author)We propose a general variational framework for the adaptive finite element approximation of fluid-structure interaction problems. The modeling is based on an Eulerian description of the (incompressible) fluid as well as the (elastic) structure dynamics. This is achieved by tracking the movement of the initial positions of all `material' points....conference paper 2006

Gerstenberger, A. (author), Wall, W.A. (author)This paper illustrates aspects of an ongoing effort to develop a fixed grid fluid-structure interaction scheme that can be applied to the interaction of most general structures with incompressible flow. After presenting a list of requirements for future fixed grid methods, an eXtended Finite Element Method (XFEM) based fixed grid method is...conference paper 2006

Blom, D.S. (author), Van Zuylen, A.H. (author), Bijl, H. (author)Strongly coupled partitioned fluid-structure interaction problems require multiple coupling iterations per time step. The fluid domain and the structure domain are solved multiple times in each time step such that the kinematic and dynamic interface conditions on the fluid-structure interface are satisfied. Quasi-Newton methods have been...conference paper 2014

Lienhart, H. (author), Gomes, J.P. (author)Experimental studies on reference test cases are of capital importance to support the development of models and coupling strategies for simulations on fluid-structure interaction problems. The need for experimental test cases specially addressed for the validation and diagnostic of numerical tools has triggered the present contribution to design...conference paper 2006

Scholcz, T.P. (author), Van Zuijlen, A.H. (author), Bijl, H. (author)High fidelity analysis of fluid-structure interaction systems is often too timeconsuming when a large number of model evaluations are required. The choice for a solution procedure depends often on the efficiency of the method and the possibility of reusing existing field solvers. Aggressive Space-Mapping, a technique originally developed for...conference paper 2011

Kreeft, J.J. (author), Weghs, M. (author), Van Zuijlen, A.H. (author), Bijl, H. (author)Two reduced order models are presented for the simulation of physically strong coupled fluid-structure interaction problem, based on computationally partitioned flow and structure solvers. The reduced order models used are a class of quasi-Newton coupling methods to obtain a stable solution and to reduce the number of subiterations. The second...conference paper 2011

De Boer, A. (author), Van Zuijlen, A.H. (author), Bijl, H. (author)In fluid-structure interaction simulations the meshes at the fluid-structure interface usually do not match, because of the different mesh requirements for the flow and structure. The exchange of data over the discrete interface becomes then far from trivial. In this paper we investigate the difference in accuracy and efficiency between a...conference paper 2006

Van der Zee, K.G. (author), Van Brummelen, E.H. (author), De Borst, R. (author)Numerical simulations of fluid-structure interaction typically require vast computational resources. Finite-element techniques employing goal-oriented hp-adaptation strategies could offer a substantial improvement in the efficiency of such simulations. These strategies rely on dual-based a-posteriori error estimates for quantities of interest....conference paper 2006

Sterenborg, J.J.H.M. (author), Van Zuijlen, A.H. (author), Bijl, H. (author)In order to validate fluid-structure interaction solvers, a one degree of freedom (1 DOF) aeroelastic experiment is performed. A rigid wing with an harmonically actuated flap, is suspended by springs to allow a free heaving motion. Displacements and time dependent aerodynamic forces are measured for reduced flap frequencies ranging from k = 0.1...conference paper 2011

De Borst, R. (author), Hulshoff, S.J. (author), Lenz, S. (author), Munts, E.A. (author), Van Brummelen, E.H. (author), Wall, W.A. (author)The basic idea of multiscale methods, namely the decomposition of a problem into a coarse scale and a fine scale, has in an intuitive manner been used in engineering for many decades, if not for centuries. Also in computational science, large-scale problems have been solved, and local data, for instance displacements, forces or velocities, have...conference paper 2006

Michler, A.K. (author), Dwight, R.P. (author), Heinrich, R. (author)The accurate prediction of the aerodynamic coefficients under cruise conditions is of major importance for assessing the aircraft’s fuel consumption.
