I have been trying with all combinations I could think of. The only way it is working is when I bond the surface over the trailing edges and half over the leading edge, which really limits the...

It has the same problem, at the second time that the structural solver runs, the "excessive distortion" error message comes up (this time, at equilibrium iteration 4 instead of at equilibrium...

I changed the order of the solvers, so that CFX solves first. The first coupling iteration worked, and it was after the second stagger iteration when the structural solver gave the error message of...

I checked again the 1-way FSI solution. The pressure load was imported, and I chose the option "Tabular Loading = Stepped". The total forces transferred from the CFX solver are FX = 0.15E-2 N and FY...

I am not sure if it is the case, because what I am trying to solve with the coulpling is a steady-state itself (I mean, the velocity field does not change).

If I try changing the order of the...

Thanks for your answer.

At the first iteration there are yet no forces applied. At the second iteration, the forces on the nodes are:

FSI Simulation of a 2D airfoil

Hi everyone,

I am doing a FSI simulation using CFX and the Structural solver from ANSYS. The problem is a 2D airfoil, leading and trailing edges are solids (structural steel) and the covering is a...
