There is a significant external imbalance force in X-direction which will be balanced by the application of opposing inertia forces. Unless your model is under such a force or under marginally imbalance forces, application of Inertia Relief may later the characteristics of your model. Do you wish to continue?" If I say no then the simulation won't finish, if I say yes it completes and the model deflects like how it should...however I am not 100% sure of the results based on that message. Any advice?
