Abstract

En 中文

• Developed a 3D numerical framework using Cartesian grids, VOF, and bond-based peridynamics to simulate complex vehicle ice-breaking and water-exit processes. • Implemented a hybrid MPI/OpenMP parallel strategy combining 2D domain decomposition with shared-memory multithreading to enhance computational efficiency. • Demonstrated that the hybrid approach significantly reduces wall-clock time and communication overhead compared to pure MPI, especially in large-scale simulations.
