Reply To: 1-way FSI from Transient Structural to Fluent

[Rahul Mule]

Hello Adamya,

System Coupling manages the coupled analyses. During execution, System Coupling performs a variety of one-way and two-way data transfers between coupling participants.

A one-way coupled analysis has a data transfer in only one direction between the coupled participants. The source region is defined only on the participant sending data and the target region is defined on only the participant receiving the data. Whereas, a two-way coupled analysis has data transfers in both directions between the coupled participants. Source and target regions are defined on both participants.

Transferring data from Mechanical to Fluent with direct schematic connection in workbench is not supported. But It can be done with system coupling by defining data transfer in only one direction between the coupled participants.

I recommend going over these tutorials in the Ansys documentation that shows a 2-way FSI simulation with Fluent and Mechanical.

Hope this helps!
