Hi everybody, I work on bilame based on Ti and Cu, I try to observe buckling under COMSOL 4.2a. I have make geometry, materials, physics,... and I make my study in stationnary. All my study include non-linear geometry. Nevertheless, when I try to launch my study, I work in continuation mode for a range from [500,-0.1,320] (Kelvin) and I obtains buckling, but when I reverse my windows from [320,0.1,500] nothing take place. Is somebody have an idea about what it is? I can send my COMSOL project if need. Thanks a lot. Jean-Philippe.
