Whats wrong with FSI? Well.... in your case your mesh has folded:
+--------------------------------------------------------------------+
| ERROR #001100279 has occurred in subroutine ErrAction. |
| Message: |

| 0. A folded mesh has oc- |

+--------------------------------------------------------------------+

Try to improve mesh quality at the location that folded.
Check that the deformation you get is reasonable.
