Hello All, I have a simply supported model for composite beam and I have to find the Load vs angle of twist (displacement) for the same. As during the experiment there was some imperfection that lead to an angle of 3.91 degrees at 0 loading. How do I add the imperfection in Abaqus model so that my displacement starts at the value of 3,91 at 0 loading? I am running a Static Riks Analysis for the same. Any help would be greatly appreciated. #help
