Whilst running my large displacement static simulation, i encountered a problem.

as shown in the first picture i'm simulating a seat rails, the grey part in the picture is bolted to the bodem plate, and the grey and green part don't have direct interaction when there is no force acting on them

The force in this simulation has a x,y and z component with Y being by far the biggest. (20.000N)

The bodem plate is fixed and the component on which the force acts is bolted to the rails. (here gray but that is the same part as the green in previous picture.)

The problem i am encountering with the simulation is that i can't get solidworks to encorporate the rails which is bolted to the bottom plate in the simulation with a result of this

so there is no interaction between the two rails, when there obviously should be.

i've tried setting no penetatrion contact set but that didn't help either.

Does anyone know how i can make it clear to solidworks that the rails will  take up a part of the stress and prevent excessive movement like this?
