Default buoyancy calculation

Hey, guys, I am simulating a box floating on a running channel flow. the box is quite big, and dynamic meshes and VOF are used here. I try to use UDF to calculate the forces working on it and then to describe its movement. But how can I get the buoyancy here? I don't want to integrate the pressure around the box, since that would include the lift force. Any suggestions?
