Abstract

Coupling of a fluids BEM code with a structural FEM code for fluid-structure interaction simulation G.L. Chahine, K.M. Kalumuck, R. Duraiswami DYNAFLOW, Inc., 7210 Pindell School Road, MD f 07JP, ABSTRACT We have developed computer programs (2DynaFS, 3DynaFS) to study poten- tial nonlinear free surface flows in axisymmetric and three-dimensional geome- tries, and have applied them to the study of the dynamics of bubbles and their interaction with nearby bodies. In previous research, the neighboring structures were modeled as rigid boundaries with no motion or only simplified motion. How- ever, the structural response can be important, and could significantly affect the bubble dynamics. Reliable prediction of loads on materials requires fully cou- pled fluid- structure modeling. In this paper we report our progress in coupling these BEM based fluid codes to existing finite element structural codes (NIKE2D, NIKE3D), and the modifications required for the modeling of both t
