Hi,

I need to run OF with fsi 6dof without mesh deformation, ie the entire grid moves as a whole. Is this possible?

I tried to modify the wingMotion tutorial by changing:

innerDistance 1e5;//0.3;
outerDistance 1.1e5;//1;

but the solution diverges after t=0.06. I checked and found that the internal mesh is moving as a whole but not the boundary.

So is it possible? the reason for doing this is because i need to simulate a wing with aileron deflection. In the mesh, the aileron deflects thru mesh deformation (displacementLaplacian). Thru FSI, the wing should rotate and the whole mesh should move as a whole. If the mesh deforms, this will reduce the grid quality severely.

Thanks.
