Wing Rib FEA analysis

Hello, I am currently working on my thesis which includes strucutral analysis of wing rib and optimization. I have already performed CFD simulation of airfoil to obatin lift and drag coefficient's.

My models consist two shell ribs, Nose and Rear rib, conected via MPC to mimic assembly conection with rivets.

My question is how should I apply lift and drag forces? I have considered applying them at the aerodynamic center (x/c=25) scoped to the wing flanges, to mimic real world sitation when skin transfers loads to the rib throught flanges. A,B and C are supports.
