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.


Best Regards,
Awais Yousaf

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.
