“…If they are identical, the same formulation can still be used. If the structure is represented by a 3D continuum model instead of a membrane model, the formulation above would still be applicable if the domain integrations over 2E and 2I in the last two terms of Equation (27) are converted to boundary integrations over 2E and 2I . In such cases, h h 2E would represent the prescribed forces acting 'elsewhere' on the surface of the structure.…”

SUMMARYThe space-time fluid-structure interaction (FSI) techniques developed by the Team for Advanced Flow Simulation and Modeling (T AFSM) have been applied to a wide range of 3D computation of FSI problems, some as early as in 1994 and many with challenging complexities. In this paper, we review these space-time FSI techniques and describe the enhancements introduced recently by the T AFSM to increase the scope, accuracy, robustness and efficiency of these techniques. The aspects of the FSI solution process enhanced include the deforming-spatial-domain/stabilized space-time (DSD/SST) formulation, the fluid-structure interface conditions, the preconditioning techniques used in iterative solution of the linear equation systems, and a contact algorithm protecting the quality of the fluid mechanics mesh between the structural surfaces coming into contact. We present a number of 3D numerical examples computed with these new stabilized space-time FSI (SSTFSI) techniques.

“…In general, the boundary does not coincide with these grid points. In our implementation, the fluid boundary is described by a polygon that is used for interpolation or extrapolation of the unknowns f i (t, x) [44]. The structural solver, on the other hand, utilizes an explicit geometric description of its boundary.…”

SUMMARYOver the last decade the Lattice Boltzmann method, which was derived from the kinetic gas theory, has matured as an efficient approach for solving Navier-Stokes equations. The p-FEM approach has proved to be highly efficient for a variety of problems in the field of structural mechanics. Our goal is to investigate the validity and efficiency of coupling the two approaches to simulate transient bidirectional Fluid-Structure interaction problems with geometrically non-linear structural deflections. A benchmark configuration of self-induced large oscillations for a flag attached to a cylinder can be accurately and efficiently reproduced within this setting. We describe in detail the force evaluation techniques, displacement transfers and the algorithm used to couple these completely different solvers as well as the results, and compare them with a benchmark reference solution computed by a monolithic finite element approach.

Abstract. We present experiences with an annual group project with a strong software engineering touch, recently established in the curriculum of the BGCE honours program, and its impact on the CSE education. The participating students organize themselves as a small software company and work on a topic provided by a specific customer of the project. For example, this year's project aims to develop a flexible geometry handling component to be used in fluid-structure-interaction simulations.
