Hello!nThanks for your reply, I will definitely try that option.n Anyway, I do not understand why it is not necessary to fix any rotation. I would say that the nodes at the edges of the holes should have fixed rotations around global x- and y-axes as in the 3D solid model, the internal faces of the holes have null axial displacement, what's incorrect in my reasoning?.Regards,nAlberton
