基于INTESIM-GISCI的流固耦合仿真软件技术及应用

Technique and application of fluid-solid coupling simulation software based on INTESIM-GISCI

为突破传统商业软件流固耦合分析仅局限于内部预先集成的流体和结构求解器的约束,使流固耦合分析更具开放性和可拓展性,以耦合驱动程序INTESIM-GISCI为框架体系,在开源流体求解器SU2的源代码上加入时间同步点和相关函数功能形成INTESIM-SU2,使INTESIM-SU2可以与原有的结构求解器INTESIM-Structure通过耦合界面传递数据的方式进行耦合分析,从而实现基于耦合驱动程序INTESIM-GISCI的流固耦合仿真软件开发。将多个流固耦合分析案例与其他商业软件进行对比,证明基于INTESIM-GISCI的流固耦合仿真软件可广泛应用于实际工程问题的仿真分析。

To break through the constraint that the traditional commercial software only provides the pre-integrated fluid and structure solvers for fluid-solid interaction analysis,and make the fluid-solid interaction analysis more open and expansible,the time synchronization points and functions are added to the source code of open solver SU2 to form INTESIM-SU2 using the coupling driver INTESIM-GISCI as the framework system. INTESIM-SU2 can be coupled with the original structure solver INTESIM-Structure through the coupling interface to transfer data. The fluid-solid coupling simulation software based on the coupling driver INTESIM-GISCI is developed. Several cases of fluid-solid coupling analysis are compared with other commercial software. The results show that the fluid-solid coupling simulation software based on INTESIM-GISCI can be widely used in practical engineering issues.
