Hello Guys,

Recently I am working on "form finding of Great belt suspension bridge" for my master's thesis using Teddy ASE example. I am facing the following problems with this geometric nonlinear analysis,

1. how can I define load case direction opposite to global Z direction(gravity direction is Negative Z)?
2. how to find factor of stiffness and prestress forces in cables?
3.how to find "STEA the normal force stiffness component"?

I have tried to find the algorithm for geometric nonlinear analysis using third order theory, but unable to find the suitable one with above parameters. could anybody help me with these questions. your assistance will be greatly acknowledged.

with kind regards,
