How can I apply the same force on multiple objects in Simscape Mulitbody?

Hi,

I am trying to apply a force that has been calculated by a simulink model to multiple bodies of my Simscape model.

Imagine a chain of thin identical plates. I want to apply a force acting on each plate in the centre of mass (CoM). When I connect the CoM frame of each plate to my force source I get an error message saying this:

I don't know how to solve this. Any help would be much appreciated.

Thanks in advance.

The problem is not with the force block. The problem is caused by incorrect configuration of the components, i.e., the components are connected in such a way that the whole structure is rigid. Most likely errors are in the orientations of the Revolute Joints, which is only free to rotate in its z-axis.
