Whats wrong with FSI? Well.... in your case your mesh has folded:
+--------------------------------------------------------------------+ | ERROR #001100279 has occurred in subroutine ErrAction. | | Message: | | CFX encountered the error: | | 0. A folded mesh has oc- | | curred. This process will shut down as soon as possible. | | | | | | | +--------------------------------------------------------------------+ Try to improve mesh quality at the location that folded. Check that the deformation you get is reasonable. |
