hey, it takes some time because of the number load steps / load curve. Also there is this critical point of buckling. You should consider to decrease the load value or increase the stiffness of the shell. I assume that your goal isn’t to produce a snapthrough. Furthermore, you could decrease the u-refinement to e.g. 3 in order to save some dofs.
