Dear All,

I have difficulty in converging my FSI case. I am doing FSI modelling in the artery models. I used linear elastic material for the artery wall with 0.2 MPa; however, it did not converge with 100mmHg and 50mmHg pressures at inlet and outlet, so I reduced the pressure to 10 and 6 mmHg at the inlet and outlet respectively. Now, I want to use the results of the converged case as initial condition for the first case (diverged case).

What I did, on the solution screen, I chose the cfx and db files as the fluid and structural initial conditions. But it gives disconnection error between Ansys and CFX at the beginning of the solution.

Could anybody help me where the problem originates from.
Regards,
AshtonJ
