Hello,nIf your question is how to access the Cornell tutorial for setting-up a 3D transonic flow over a wing, then this content in the link you are sharing has been moved to a new location. Here is the new location to this same Cornell content (same link that I already shared with you in my earlier post). You should be able to go through this tutorial and learn about how to model a 3D wing and generate the lift force distribution..nIf you have a specific question.please create a new post and we will be happy to help you with it.nThanks.nKarthikn
