Najm gave more information on the question:
My apologies. I should have been more clear.

I am running a hydraulic fracture model using YADE. The model is a square domain (2D) which is filled with spheres. I am now contemplating on what to do with the boarder edges. One option is to keep them free, but this causes rigid body motion. Another option is to pin the spheres at the edges, but the model size has to be very large for the edge not to interfere with the crack. 
One option is to implement infinite FEA elements on the edge to model a infinite domain. I was wondering if YADE has this capability or if anyone in the community had done this. 

All I want is the edge spheres to experience a reaction force, during
deformation, as if the domain is infinite.
