Erik Thanks again for the support! After simplifying down to only the supports and running a combination of different loading conditions I have finally identified the issue. Instead of using the built-in Standard Earth Gravity conditions, I used the generic Acceleration condition with components [0,0,-9.81] m/s^2, thinking this would be equivalent, but that's not the case. You need to accelerate the bodies upward to feel the opposing downward force. Once I figured this out I searched and found the following answer: https://forum.ansys.com/discussion/11409/difference-between-standard-earth-gravity-and-acceleration
