I am using System Coupling. But when I select one region from Structural and one from Fluid, I only get 1 Data Transfer isntead of 2...Previously, I used to automatically get 2 Data transfers. What should I do?

 

 

Am I doing anything wrong? I could not find any info on the OPTION of choosing 1 Data trasfer (1 way FSI) or 2 Data trasfer (2 way FSI). How does the Ansys SC knows I want 2 way or 1 way? Its very weird.... Thanks!!

I guess input topology is missing in Fluid flow region for System coupling FSI. But idk how to correct it?

• The System Coupling option must be selected on the desired moving and deforming wall boundaries in order to obtain displacements from other co-simulation participants taking part in the coupled analysis.

• The via System Coupling option must be selected on the desired wall boundaries in order to obtain heat transfer data (temperature, heat flow, or heat transfer coefficient) from other participants taking part in the coupled analysis.

Check your Fluent settings. Provided correct settings and then you should be able to create required data transfer.
