Poisson's Ratio of RVE of periodic lattices using perioidic boundary condition in COMSOL

I have applied periodic boundary condition to 3D RVE of 3D periodic lattice structure in COMSOL.

If I apply strain in x direction, I always get very small strain in other two direction, almost 0 value. Which means my Poisson's ratio is zero?

Is this right? How to identify Poisson's ratio of periodic structure?
