  Hi all -
  
  I am using ANSYS 19.0. I followed this tutorial:
  
  However, when I run the co-sim from system coupling, it crashes and says there was too much distortion from the structural element. What is causing that, and how can it be rectified?
  
  Thanks!

  Obviously, distorted elements caused the structural solver divergence. This error might have already manifested itself in the fluid solver by large mesh displacements and large forces passed to the structural solver. This might be alleviated though smaller time scaled, deployment of stabilization methods and implicit updates in Fluent. You can ask the author for the workshop files to check your settings.
