Hi, I'm performing a three-point-bending test in 2D, but the model was floating so I added an earth gravitational force, amongst the suggestions provided in my previous post: \/forum\/discussion\/comment\/131420<\/a>.However, the gravity force is making my model (the middle bar\/specimen) disappear during the unloading phase. It's shifting very far downwards. Probably I'm missing a constraint or boundary condition, but I can't figure out on my own what the problem is. Is there a boundary condition missing in my setup?<\/p>\n

B=fixed.<\/p>\n

C=-2mm displacement in 2 steps.<\/p>\n

D = 0 displacement in x direction.<\/p>\n

Two frictional surface contacts are defined.<\/p>\n
