Sequential Analysis (Linear)

rebel

Hello, I am performing linear-static analysis in a system includes pbush elements. Firstly, I need to apply  pre-stretchings to my pbush elements, after that, I need to apply gravitational load to my pre-stretched system. How can I set a sequential analysis like this in the load step? Or, how can I use the pre-stretched output results and configuration as an input for gravitational loading?

Thanks,

you can create the pre-stretched subcase first,and then create the subcase for gravitational load,and you can see that there is a option named STATSUB(PRELOAD),click the check box and select the pre-stretched subcase
