I have modified pimpleDymFoam into a FSI solver, the solver works for Euler temporal discretization but fails for any second order scheme.

I am using TVD spatial schemes (limited linear) and unstructured grid with temporal scheme with timeadjustable on.

The result I get when apply backward is that the pressure diverges for a few iterations whenever update is called.

Case solved: sliding mesh boundary condition caused the pressure oscillation.
