Two-way fsi

kapeciolo · March 25, 2017, 13:41

I am trying to do two-way fsi analysis in ansys workbench. I only saw examples when there is coupling between the structural load and fluent while the structural load was applied manually. What i was trying to do is to use the imported load from fluent to my transient structural, but i cannot make it work. Did anyone do something like this before. If so , can you give me a tip of how to perform such an analysis?

Hello kapeciolo,

I don't know whether you have seen this website. But, I hope this will help you.

This site contain two parts, one for CFD simulation and one for structural simulation.

if you see it carefully,in both case, he has kept the mesh pattern same on blade surface for CFD and structural simulation.

I hope this will help you.

You need to use the system coupling block to loop the forces from Fluent back to the transient structural solver.

I have managed to do it like it , it worked
