work with deformed geometry

Please login with a confirmed email address before reporting spam

Dear Colleagues,

I have to perform nonlinear analysis on thin walled columns. Before performing this study I need to model geometric imperfections. I want to follow this procedure:

1) perform a stationary study where I model imperfections
2) export deformed geometry (because in nonlinear analysis I want to study my deformed geometry without stresses born from step (1))
3) perform nonlinear study

So, is it possible to do that? I have a solid model and I need to use a particular mesh (prismatic element, quadratic shape functions and only one finite element along the thickness).
I tried to use “Remesh Deformed Configuration”, but seems to work with tetrahedral elements only. I must use prismatic element because I have a better description of the problem with less, many many less, degrees of freedom.

Thanks for any suggestions (or for alternative methods to solve that problem).

Simone
