Hi, Foamers,
I recently get on with FSI issue, in OpenFOAM there are two solvers for FSI (icoFsiFoam and the other designed for large deformation, name too long).
So the question is: How can we define a defromation a large deformation? I mean in what circumanstance shall we choose between the two solver?
BTW, the two solvers will coincide with each other for small deformation?

waiting to be replied.

Thanks.
