Recently, I was trying to compute the equivalent elastic properties of random chopped-fiber reinforced composite（The 3D SG model is shown in the figure）. I found that when the number of elements or nodes in the model is large and the sc.k file calculated by homogenization is empty. I would be very happy if you could answer my question.
