Discrete Data Transfer Technique for Fluid-Structure Interaction

Abstract: This paper presents a general three-dimensional algorithm for data transfer between dissimilar meshes. The algorithm is suitable for applications of fluid-structure interaction and other high-fidelity multidisciplinary analysis and optimization. Because the algorithm is independent of the mesh topology, we can treat structured and unstructured meshes in the same manner. The algorithm is fast and accurate for transfer of scalar or vector fields between dissimilar surface meshes. The algorithm is also applicable… Show more

“…When aerodynamic pressure is calculated using CFD, the data transfer technique is required for the state variable conversion such as pressure onto the nodes of FE mesh because of dissimilar meshes between CFD and FEM. [21] As shown in Fig. 9, the aerodynamic load is transferred on each node of FE mesh from three nearest nodes of CFD mesh, which are found through a spatial proximity search.…”

“…The line loadsl aerodynamics are computed by integrating nondimensional pressure coefficients from the vehicle surface using the FUN3D solution. 28 Further details regarding the data transfer, the static aeroelastic solution method and FRILLS formulation are discussed elsewhere. 9 In the quasi-steady formulation the dynamic response of the vehicle can be computed by linearizing the line loads around the local static α l , β l and static generalized force G s .…”
