Reaction at the interface between two elements!!

Hello,

I'm realitevely new working with Code Aster and I'm having troubles obtaining the reactions at the nodes of an interface between 2 elements. The REAC_NODA gives me the difference reaction between this two elements at the node (what it is super close to zero due to the equilibrium in the system), but what I need is the reactions in each element separeted...my example (for simplicity) is just a rectangle meshed with 2 elements, and I need to take one element and see what it is going on with the reaction on it.

Thanks in advance

p.s: I have look a looooot of aster documentation and forum, but it seems that I'm not understanding something
