There is one more question that I would like to ask you and if needed I will create a new discussion. nIn an already converged analysis of the artery-stent assembly, when I try to add a new connection and run another simulation, there seems to be an unjustified event. nWhile the new connection is between the balloon and the stent, the artery is also deforming when the balloon is moving, without even touching the geometry of the stent or the balloon. This remote movement seems to appear only at steps where the new connection is alive. Even if I remove any relation between the balloon and the artery, the remote deformation still occurs. nI have faced this kind of problem several times and it would be valuable of you had any idea about the nature of the problem.nThank you! n
