Hello!
Is it possible to do a 1-way FSI analysis with the loads being transferred from solid to fluid? Essentially, I have a solid body which deforms in a certain way (inside water), and I want to see how that solid body deformation affects the fluid around it. So can I have a data transfer from solid to fluid instead of the other way around?
Thank You

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!

Hello Mr. Rahul
Â
Thank you very much for your help and response- it is very helpful! Noted on your instructions- I will use a single data transfer from Mechanical to Fluent. Many thanks for sharing the tutorials as well, I shall certainly take a look.Â
On a slightly different tangent, could you please answer one more question- can I apply displacement across time to a 3-D body's centerline to induce a deformation? For example, I have a solid body (a curved tube) who's centerline coordinates (and curve equation) are known across time. Can I use that to induce the motion? Then I plan to transfer this to Fluent to see the motion's effects on the fluid.Â
Thanks a lot :)
