基于高性能计算的水下爆炸数值仿真

摘要

Cluster technique supplies a high performance computing ( HPC ) platform for numerical simulation of underwater explosion. Based on the HPC cluster system and parallel calculation of underwater explosion ( UNDEX) using ABAQUS code, the performance test and result verification of HPC were conducted using the scaled model of a surface ship. The best optimization scheme was found out for the specific calculation size. The conclusion can provide a reference for UNDEX numerical simulation of large computational size model to gain more accurate result.%集群技术为水下爆炸数值仿真提供了强大的高性能计算平台.基于高性能计算集群系统和ABAQUS水下爆炸并行计算技术,对遭受水下爆炸的舰船缩比模型进行了性能测试和算例验证,给出了针对特定计算规模的并行计算优化方案.该文研究结果为舰船水下爆炸的高精度数值仿真提供参考.
