Abstract
The ALE description is adopted for the fluid domain,while the Lagrangian formulation is considered for the structural domain.The computation of fluid-structure interaction is realized by the penalty function-based coupling method.The dynamic be- haviors of the dual layer liquid-filled container in the crash is analyzed,in the meantime,the parallelism of the dual layer container is discussed because the computation of fluid-structure interaction and the impact contact is quite time-consuming.Based on domain decomposition,the recursive coordinate bisection(RCB)is improved according to the time-consuming characteristics of dual layer liquid-filled container in the impact with the ground.The result indicates,in comparison with RCB algorithm,the improved recursive coordinate bisection(IRCB)algorithm has improved speedup and parallel efficiency.
