Hi everybody,

I currently used Comsol to see the force_displacement relation of a bistable nonlinear-cantilever beam,
If I sweeping by varying the Force and then caculated Total Displacement, I cannot get the unstable solution.

I thinks that I should sweep the Displacement and then calculated again the Force. It will be better.

So, I set "Precribed Displacement" as I desired, and "include nonlinear geometry" and calculated the "Reaction Force", however, I am not get correct results ( compared with Force sweep),

And also, if I set "Precribed Displacement" in boundary or in edges, it give me different results,.

Hope that you have some experiement about this to help me ?

Thanks
