Co-Simulation Interface Reduction Based on the Flexible Natural Coordinates Formulation

EasyChair Preprint 13457

Abstract

Combining structural simulations with distributed load models within a co-simulation framework typically necessitates the exchange of substantial sets of input and output data. These data sets, which scale with the size of the corresponding structural finite element mesh, can become a critical factor affecting overall simulation time. To mitigate the data exchange burden in the co-simulation interface, we propose a reduction method based on model order reduction techniques found in small deformation flexible multibody formulations. Consequently, the regarded structural model is subjected to the same limitations as small deformation flexible multibody models. The proposed methodology is implemented using the Flexible Natural Coordinates Formulation (FNCF), resulting in a co-simulation interface reduction strategy that limits the required interface points while maintaining the same level of accuracy.
