applying drag force in fsi simulation

In my simple 2D fully-coupled fsi transient simulation, a body is moving due to reaction force. It moves 'more' than what it has to. I think i have to manually apply drag force due this resultant motion.
somebody please point me how would I calculate drag force and how will I apply back to the body (point load/ volume force or something else)?

Theory says that this could be Lift-induced drag (also called induced drag) that occurs due to the creation of vortices (vortex drag) and the presence of additional viscous drag (lift-induced viscous drag).
How can we calculate in Comsol?
Mr Ivar could you please?
