“…This motivates the implementation of interpolation between non-matching discretizations. It should be noted that the interpolation of fields on the non-matching interface may compromise the accuracy of the whole simulation [46], and several authors have addressed the problem of coupling two non-matching discretizations [1,[46][47][48][49][50][51]. The general criteria for choosing the appropriate interpolator relates to its efficiency, robustness, accuracy, and conservation of momentum and energy [1,46,49,52].…”

“…It is a common approach in the literature to apply the principle of virtual work [1,46,49,53] to define a conservative transfer scheme. Brown [52] and Farhat [1] have introduced projection methods that apply the conservation of virtual work to the problem of transferring load and deformations in FSI problems on non-matching meshes.…”

“…According to the previously described principle of virtual work, the tractions at the structural interface may be mapped from the fluid domain as λ s = H T λ f . Therefore, it is possible to define a full space-coupling scheme that would meet the criteria of conservation of work by adequately defining a transformation matrix H. Global conservation of forces can also be achieved by imposing that the rowsum of H is equal to one [49].…”

Abstract. We report on an international effort to develop an open-source computational environment for high-fidelity fluid-structure interaction analysis. In particular, we will focus on verification of the implementation for application in computational aeroelasticity. The capabilities of the SU2 code for aeroelastic analysis have been further enhanced both by developing natively embedded tools for the study of largely deformable solids, and by wrapping it using Python tools for an improved communication with external solvers. Both capabilities will be demonstrated on relevant test cases, including rigid-airfoil solutions with indicial functions, the Isogai Wing Section, test cases from the AIAA 2nd Aeroelastic Prediction Workshop, and the vortex-induced vibrations of a flexible cantilever in the wake of a square cylinder. Results show very good performance both in terms of accuracy and computational efficiency. The modularity and versatility of the baseline suite allows for a flexible framework for multidisciplinary computational analysis. The software libraries have been freely shared with the community to encourage further engagement in the improvement, validation and further development of this open-source project.

“…As coupling method in this paper, we take the radial basis function method(RBF) with large compact support. This method, favored by [1], because of its accuracy and efficiency, does not need orthogonal projection or search algorithms. The coupling between fluid and structure equations arises from the dynamic and kinematic boundary conditions(BC) at the fluid-structure interface.…”

Nool, E.J. Lingen, A. de Boer, H. Bijl FLECS, a flexible coupling shell, application to fluidstructure interaction ABSTRACT Numerical simulations involving multiple, physically different domains can be solved effectively by coupling simulation programs, or solvers. The coordination of the different solvers is commonly handled by a coupling shell. A coupling shell synchronizes the execution of the solvers and handles the transfer of data from one physical domain to another. In this paper, we introduce Flecs, a flexible coupling shell, designed for implementing and applying an interface for multidisciplinary simulations with superior accuracy. The aim is not to achieve the best possible efficiency or to support a large feature set, but to provide a flexible platform for developing new data transfer algorithms and coupling schemes.

REPORT MAS-E0624 DECEMBER 2006 IntroductionFluid-Structure Interaction (FSI) considers coupled fluid-solid problems, characterized by the interaction of fluid forces and structural deformations, which occur in many applications in industry and science. Nowadays, the simulation of FSI becomes more and more important, since future structures become lighter and more flexible and can be applied, e.g., to reduce the load on turbine blades, or, to reduce the noise on cars. Such applications require a real interdisciplinary approach, that can deal with complex physical models and very different scales. The Faculty of Aerospace Engineering of the Delft University of Technology has started a project to develop a generic, open-source coupling shell, named FLECS [3], that can be used to join two or more arbitrary solvers. FLECS should provide an innovative combination of high order coupling in space and time. Moreover, to improve the accuracy and the efficiency of the computation, multilevel acceleration techniques for the coupling process [2], and fast prototyping and parallelization techniques will be supported.The majority of coupling shells are embedded subprograms that have been developed for coupling two specific solvers. One exception is the coupling library MPCCI (Mesh based Parallel Code Coupling) [5], which can be used as a separate program. Although MPCCI is relatively easy to use and provides §
