Abstract
Fluid-structure interaction is a challenge in engineering as it involves designing structures and machines capable of withstanding the associated forces during operation. To address this, it is necessary to develop models that couple fluid dynamics with solid dynamics. One important aspect of this coupling is the transfer of loads and displacements between the fluid and solid domains, which may differ in detail and topology. The purpose of this paper is to provide a comprehensive description and substantiation of a mesh mapping technique that enables information transfer between the Giraffe structural solver and the OpenFOAM fluid dynamics solver. This technique utilizes a mesh-less mapping approach based on weighted least-squares minimization, employing radial basis functions as weights and polynomial functions as basis functions. To demonstrate the effectiveness of this approach, a test case involving an elastic strip with simple geometry and imposed load is presented. The test case focuses on observing the transfer of load and displacement between the fluid interface mesh and the structural beam mesh. The results of the test case confirm the successful achievement of the objective, showcasing the accurate transfer of beam displacements and the forces present in the fluid interface mesh.
