I have school project, frame similar to container frame with two vessels inside. Both vessels are suported on two beams in 4 points. What is recommended way to represent impact of weight of vessels on frame so structural analysis is correct. To devide total weigt of vessels by 4 and place that force on each supporting plate or to use remote force to represent weight of vessel.

I know only mass and center of gravity of vessels. I don't have model, just model of frame.
