摘要: 针对复杂工程问题数值模拟中网格数量多、计算耗时长的问题,结合流体仿真软件(Fluent)中UDF(User-defined Function)并行计算原理与UDP(User Datagram Protocol)通讯,通过嵌入UDP通讯的UDF与S函数完成了Fluent与可视化仿真工具(Simulink)之间并行计算的数据的传递,搭建了盘坯气体冲击射流淬火并行计算仿真平台,并对同一模型分别进行了串行与并行计算,完成了数值模拟结果对比分析,验证了并行计算仿真平台的可靠性和有效性,可为复杂工程问题的数值计算提供思路。

Abstract: Aiming at the problem of large number of grids and long computation time in numerical simulation of complex engineering problems, combining the User-defined Function (UDF) parallel computing principle with UDP (User Datagram Protocol) communication in Fluent, the data transfer of the parallel calculation between Fluent and the visual simulation tool (Simulink) is completed by embedding UDF and S function in UDP communication. And the parallel calculation and simulation platform of the disk and billet gas impingement jet quenching is built. The serial and parallel calculation of the same model are carried out, and the comparative analysis of the numerical simulation results is completed. The reliability and effectiveness of the parallel computing simulation platform are verified, which provides a way of thinking for numerical calculation of complex engineering problems.

Key words: parallel computing, co-simulation, Fluent, Simulink, gas impact jet quenching
