Abstract
In this article an investigation of possible coupling strategies for large numerical models in fluid-structure interaction is given. The focus is on the development and the assessment of a simplified approach that uses existing and well verified scattered data interpolation methods. The interpolation problem is addressed by a pragmatic partitioning approach of large models. Analysis of the interpolation of deflections between different discretization of the coupling models are performed, together with comparisons of static fluid-structure simulations with measured data of the elastic DLR-F12 wind tunnel model. The loads transfer between CFD mesh and FE model for different partitioning schemes is performed and assessed, finally some considerations for the use of the suggested strategies on large models are presented.
