I have an odd problem. I am trying to recreate the Large Deformation Beam model (www.comsol.com/showroom/documentation/model/204/) before I start my own project to investigate buckling. I was following along with the model, but when I go to Study 1 > Step 1: Stationary and open Study Settings, I do not see any buttons that say "Include Geometric Nonlinearity". Indeed, I do not see any buttons at all.
When I download the support file for the Large Deformation Beam model, I do see this button.
However, if I delete the stationary solver and add a new one, I do not see the button any more.
It seems like I must be doing something dumb here, but I can't seem to figure out what. Any help would be appreciated.
Thanks,
