Extended ALE Method for fluid-structure interaction problems with large structural displacements
Standard Arbitrary Lagrangian-Eulerian (ALE) methods for the simulation of fluid-structure interaction (FSI) problems fail due to excessive mesh deformations when the structural displacement is large. We propose a method that successfully deals with this problem, keeping the same mesh connectivity while enforcing mesh alignment with the structure. The proposed Extended ALE Method relies on a va...
متن کاملNumerical Analysis and Scientific Computing Preprint Seria An extended ALE method for fluid-structure interaction problems with large structural displacements
Standard Arbitrary Lagrangian-Eulerian (ALE) methods for the simulation of fluid-structure interaction (FSI) problems fail when the structural displacement is large. We propose an extended ALE method that successfully deals with this problem without remeshing. The extended ALE approach relies on a variational mesh optimization technique, combined with an additional constraint which is imposed t...
متن کاملAiaa 2001–1624 Shape Design Optimization of Steady Fluid–structure Interaction Problems with Large Displacements
The objective of this work is to develop and implement efficient numerical procedures for gradient based shape design optimization of steady, strongly coupled fluid–structure interaction problems. Nonlinearities in the analysis arise from both the solid behaviour, the fluid behaviour, and from the deformed interface, where the deformation of the interface is large enough to significantly alter ...
متن کاملAn Eulerian-ALE Embedded Boundary Method for Turbulent Fluid-Structure Interaction Problems
The FInite Volume method with Exact two-phase Riemann problems (FIVER) is a robust Eulerian semi-discretization method for compressible multi-material (fluid-fluid, fluid-structure, or multi-fluid-structure) problems characterized by large density jumps and highly nonlinear structural motions and deformations. Its key components include an embedded boundary method for Computational Fluid Dynami...
متن کاملA novel dual time stepping method for Fluid Solid Interaction (FSI) problems with large deformations
Despite recent findings [1] on the superiority of monolithic approaches to FSI over the segregated ones, there are many advantages that make the latter a valuable alternative [2]. For example, in a staggered approach, individual solution strategies can be employed independently to fluid flow and solid dynamics and they can be coupled through a robust interface coupling methods. This allows rese...
