I have a cylinder and My problem is that I want to implement a boundary condition of free displazament along the edge, but radially lock the displazaments, and i only know how lock the displazament long x, y or z, but not radialy.
thank you for your reply Mustaine3, I tried to do that and the thing i'm not sure is the position of the edges Ur = U1? I mean the numerical and the normal names,
