2 Way FSI Coupling
 

Hi,

I have recently started to model flow inside an artery using ANSYS Workbench through 2 way coupling.
After some run time my simulations crash due to excessive distortion in transient structural part. I have tried to refine the mesh but the model is still unstable and it crashes.

Any ideas you share will be appreciated.

i have same problems error system coupling run completed with error

Trigui,
If you look at coupling set-up in workbench, you can get more details regarding the error from individual solver. Look at the error there and you can then narrow down the issue.

Cheers!

I am suggested to use RBF morpher - ACT Ansys Mechancial RBF morpher extension.
