thank you for answering. I completely understand what you said, and I was already aware of this phenomenon that when the force does not pass through the centroid of scoped faces, then there has to be a net moment generation and the solver will automatically determine how the extra force which is the equivalent of this moment will distribute over the scoped faces (since it becomes somewhat tedious to calculate the force distriibution onto the scoped faces from moment by hand, if there are a large number of scoped faces.)
What I had the problem with is that why would a RIGID remote force (as shown in this thread) still result in the different force transfer between the two surface bodies? What you explained makes sense for a Deformable remote force, where the two bodies can behave independently from each other once the force distribution from the remote force is done, but for a Rigid remote force, I don't think that the force distribution should be calculated in the same way as like in the Deformable case. Moreover, as I already have mentioned in the thread, that both bodies have the same deformation, same material, same dimensions, then what is the reason that still they have different force transfer? Because the bodies are behaving as if the force transfer should be the same in both of them.
I hope you understood my query.
