Hi,

I'm learning to use the CFX and I'm resolving the tutorials of the program. I found something strange in the tutorial number 22 - Fluid Structure Interaction and Mesh Deformation. I followed all the instructions, but when I start the simulation it's stop after 5 iterations with two errors that I transcribe here. I would like to know why it is happens.


--------------------------------------------------------------------+
| ERROR #002100027 has occurred in subroutine cNWDIST. |
| Message: |

| Please consider improving the mesh quality. The coordinates of |
