I work with FSI in Ansys 14.0 using System Coupling, which makes the interaction part of the structure (Transient Structural) with the Fluid Flow (Fluent). But my problem is that the dynamic mesh (Remeshing), it doesn’t work. So the System Coupling gives error, because the mesh of the Fluid.

The message de error: “Update failed for the Solution component in System Coupling. System coupling run completed with errors. Additional information: One or more elements have become highly distorted. Excessive distortion of elements is usually a symptom indicating the need for corrective action elsewhere. Try ramping the load up instead of step applying the load (KBC,1).”
Or
“Update failed for the Solution component in System Coupling. System coupling run completed with errors. Additional information: Fluent encountered fatal error after sync point Solve”


Please, can anyone help me?

Thanks.

It seems that remeshing is invalid in FSI for both fluent and CFX.

it is possible to do remeshing in fluent while using system coupling.it only does not do local face remeshing at the fluid-solid interface.
