One Way FSI Analysis with ANSYS CFD & Mechanical - ANSYS e-Learning

In a fluid-structure interaction (FSI) calculation, the solid surfaces act as interfaces between the fluid and solid domains, providing the means to transfer loads- mechanical or thermal. The CFD solution provides flowfield solutions for pressure or heat fluxes on solid surfaces, and the FEA solver calculates solid deformations or temperatures based on the CFD results.

The deformed solid surfaces will in turn constitute a new boundary for CFD calculation, which can result in a different pressure or thermal loading. Thus, the FSI analysis sometimes requires two-way interactions and a fully coupled iterative solution at each time point, which can be computationally expensive.

However, one-way FSI provides an economic alternative, which can be readily used to check model validity, surface mapping, load transfer accuracy, and a good estimate of the structural response. In many cases, one-way FSI is all that is needed because the fluid and solid solutions are only weakly coupled.

In this ANSYS e-Learning session CAE Associates' CFD Manager Dr. Hsin-Hua Tsuei demonstrates the one-way FSI analysis process using ANSYS CFD and Mechanical software.
