Study and Discussion on Computational Efficiency of Ice–Structure Interaction by Peridynamic

The peridynamic (PD) theory is based on nonlocal mechanics and employs particle discretization in its computational domain, making it advantageous for simulating cracks. Consequently, PD has been applied to simulate ice damage ice–structure interaction under various conditions. However, the calculation efficiency of PD, similar other meshless methods, constrained by number particles inherent limitations method itself. These constraints hinder potential further development field ice−structure interaction. This study aims explore methods that can be employed improve cost interactions. Specifically, we analyze three different (the MPI parallelization, updated link−list search method, particle−pair method) their collaborative reduce simulation time. are calculate ice–ship interaction, coupled studied. Furthermore, this discusses computation strategy using present work provides scholars who employ or with a referential discussion plan achieve an efficient numerical process.
