I've been using the sixDoFSolver library, and coupling with pisoCentralDyMFoam as my fluid solver, and trying to solve for the elastic motion of a 2D airfoil. Despite having checked all my parameters, I've been getting results that are always diverging, and never damping.
Worse, the amplitudes of my motion seem to be off by an order of magnitude (I've checked my units), when compared to those obtained by other researchers and professionals. Attached are the forced and aeroelastic results combined for the supposedly three different speed indices that should give me damping, neutral and diverging results - has anyone else had this issue? |
