Hello,

I am new to FLUENT and would like to perform a Fluid-Structure Interaction inside FLUENT (see image attached). The problem is based on a flow around a cylinder with one DOF. I expect the cylinder to oscillate due to vortex shedding. I already managed to perform a FSI of a cylinder with 1 DOF using the 6 DOF solver via the GUI (see 2. image attached). The GUI offers spring parameters but no dapshot parameters. Can I only use the GUI for simpler FSI problems but not for more compex ones or how do I interpret the settings? Does someone know where I can find a UDF for a similar problem that allows me to provide my own motion equation based on my specific problem. Is it possible with newer FLUENT versions to compile the UDF within a workbench workflow directly without relying on the VS Command Prompt for example?

Thank you all in advance :)

As you are new to Fluent, I recommend going over this tutorial in the Ansys documentation that shows a 2-way FSI simulation with Fluent and Mechanical. Reed Valve FSI Co-Simulation with Partial Setup Export from Workbench (Fluent-Mechanical)

To learn more about UDF, you can refer to the Ansys Fluent customization manual Ansys Product Help

You can use the built-in compiler for the latest versions of Ansys Fluent to compile UDF Ansys Product Help
