Hi Saurabh,

Thank you for your reply.

The geometry is very simple, only a box. The surface I am interested in is the bottom surface, which is parallel to the xz plane.

Here are the results from the force reports and surface integrals:

 
As you can see, the forces are very different.
This mismatch seems to occur when on this surface there are 2 phases.
