      In the contact, I am selecting two cylindrical surfaces for bonded contact. But in the status, I can only see a partial section and because of this, I am having weird stresses in that area, with only applying bolt pretension. The two surfaces are line on line, the accuracy of the model is 0.0001. Please suggest what to update to see full circular contact between the surfaces.
