Using the Large Deformation Analysis we can simulate the behaviour of a hanging model to find the optimum form for the applied stresses. The principle stress lines of the shell can be viewed after the analysis. For viewing in the FREE Version use a Analyze Model component instead of the Optimize Cross Section component. For viewing in the Trial Version set the Mesh Resolution of the Mesh Breps component to 10.
