MFX-ANSYS/CFX流固耦合计算及其在“魔方”上的应用

流体和固体之间的耦合作用在工程领域中有非常广泛的应用,对这类问题的求解一直是工程上的难点。本文介绍了一种流固耦合求解方法,采用CFX和ANSYS软件分别对流体域和结构域进行求解,其耦合面的数据交换以MFX-ANSYS/CFX为平台,并通过实例验证了流体和结构之间的耦合效应。同时,基于"魔方"高性能计算平台,探讨了这类问题的并行求解算法以及在不同处理器数目下的计算效率,为该类方法的大规模计算以及更好地发挥并行计算优势提供参考。

The MFX-ANSYS/CFX Fluid-Solid Coupling and Its Application in "Magic Cubes"

The coupling effect between the fluid and solid has a very wide application in the engineering field,but the solution of such problems has been the difficulty of engineering.This paper first introduces a solving method for fluid-solid coupling,adopts the CFX and ANSYS software to solve the fluid domain and structural domain respectively,and completes the data exchange in fluid-solid coupling surface by MFX-ANSYS/CFX.Practical examples show this method is effective.The coupling effect is coincident with a typical application example and the results show that this method is effective.In the end, based on the"Magic Cube"high-performance computing platform,the computational efficiency of this method is discussed under the different number of processors,which provides helpful reference for largescale computing and parallel solution of this method.
