Hi Ben Fixed axially is a problem because as the balloon expands it gets shorter and the axial constraint is preventing that from happening.
Use two remote displacements, Behavior = Deformable. You don't show the axial coordinate direction, but assume it is Z.
One remote displacement is scoped to the edge at one end and sets X, Y, Z and Rot Z to 0 leaving the other two free.
The other remote displacement is scoped to the edge at the other end and sets X and Y to 0 leaving the other four free.
