Hi,

I have a passenger seat with passenger mass distributed on the seat cushion through RBE element. I am doing a static analysis of the same under 1 g braking and 1 g cornering load condition.

The seat is fixed at the bottom. Gravity load is applied in lateral and longitudinal directions. 

In real scenario if this condition happens the passenger will come out of seat and the same happens on using rbe 3 with displacement of dependent node but not the independent nodes as they are attached to structure.

While making rbe3 dof of dependent node is kept fixed in all directions but still it moves? Please clarify on this .
