Hello
In the context of an EF 1D study on catia (see attached system in image), I encounter a problem when I apply a force to the structure, the deformation obtained is not the right one (see attached), there is a place where the structure comes off. So I realized that I needed to add a connection to this place, but I don't know how to do it. I tried to apply the node connection property but couldn't. Could you please help me?
