Hi 

Ensure that mesh quality is good (orthogonal quality > 0.1).

This error might be due to failure of dynamic mesh. You can modify the inputs to the dynamic mesh, refer 11.6. Using Dynamic Meshes (ansys.com) 

Please refer 42.11. Troubleshooting Two-Way Coupled Analysis Problems (ansys.com) for more info.

Hope this helps!
